Dating

Chris Pratt is apparently a hopeless romantic, who really knows how to make a girl laugh -- just ask Katherine Schwarzenegger!!

Chris was spotted on a picnic date Sunday with Arnold and Maria's 28-year-old daughter. The duo's outing went down up in Santa Barbara, and Chris was a total gentleman -- picking up Katherine at her place and driving her up the coast in his truck ... they even stopped to get gas together.

We've seen Chris get flirty before, but this is the first time we've seen him on a full-fledged date since he filed for divorce from Anna Faris back in December.

While Katherine clearly has a Hollywood pedigree, she's not IN the biz. She's an interior designer and lifestyle blogger.

Pete Davidson was technically single when he started dating Ariana Grande ... TECHNICALLY, but "Friends" fans might not agree.

Sources close to the newly engaged couple say Pete and his ex-gf, Cazzie David, were "on a break" in early May -- but not necessarily broken up for good -- when his relationship with Ariana sparked. But they hit if off, and it quickly became clear Pete was serious about moving on with Ariana.

The good news -- it seems all parties involved are happy with the end result. As we reported, Cazzie's not upset or dwelling on her ex's quick rebound. Hey, if it's good enough for Ross and Rachel.

As for Ariana and Pete -- they're still in full PDA mode with Davidson posting a pic wrapped up with his fiancee, captioned ... "u know what you’d dream it be like ? it’s better than that."

Is Rihanna missing out by not dating Joel Embiid? He seems to think so.

The following is a direct quote:

"I don't want to talk about Rihanna but, you know, I feel like every girl in the world should, you know, taste the process and see what the process is like."

Gotta love a man with confidence.

Remember, Embiid tried to shoot his shot at Rihanna back in the day, but it didn't quite work out for the young NBA star.

So, when we saw him out in Bev Hills the other day, we asked him about it -- and he made it clear he's moving on ... to EVERY OTHER WOMAN ON EARTH!

"Every girl in the world is missing out. You know you got to taste the process, you gotta see what the process is like."

John Cena and Nikki Bella's dinner date looked hard to swallow by the looks on their faces, and we're guessing it had nothing to do with the meals they ordered.

The on/off -- but lately, mostly off -- couple went out Tuesday night to the Cowboy Star Restaurant in San Diego, not far from where Nikki lives.

Witnesses tell us their conversation looked intense during the entire meal -- which could be good or bad. As we've told you .. they've been trying to work things out since Bella called off their engagement in April. Cena begged to get her back, but they haven't announced a reconciliation yet.

No denying ... Nikki did NOT look happy at this particular moment. Glass-half-full types will say they're having a tough convo that'll lead to a reunion. Half-empty peeps will say ... it's the last supper.

Ben Simmons not only ruined his chances at a reconciliation with Tinashe ... he also blew it for EVERY OTHER PRO BALLER -- because the singer tells TMZ Sports she's 100% done with athletes.

The "Faded Love" singer was leaving Delilah in West Hollywood after hitting the club on Wednesday night -- and, after all the drama with Ben, we asked her what she's looking for NEXT in a man.

"Not to be an idiot," she told us ... noting that she finds a LOT of idiots in this town.

And when we asked if that meant no more ballers, she responded ... "Oh yeah. That's 100."

For the record, Tinashe recently dropped a ton of new music with big stars like Future, Offset, Ty Dolla $ign and French Montana ... so who needs NBA stars when you've got rappers?

1:36 PM PT -- A law enforcement source tells us ... during the alleged incident, Lincoln grabbed the woman's hands and placed them on his own chest and stomach. We're told he then allegedly groped her breasts and grinded up on the woman. It all happened on a ship called Spirit of Boston.

A contestant on the new season of "The Bachelorette" -- who's still in contention -- became a convicted criminal charged with a sex crime just a week before the premiere.

Law enforcement sources in Suffolk County, NY tell TMZ Lincoln Adim was convicted of indecent assault and battery on May 21 from an incident that occurred in 2016. Adim was accused of groping and assaulting a woman on a cruise that year.

Crazy enough, his sentence was handed down right before the new season aired on May 28. Adim was sentenced to a year behind bars, with that term being suspended for a two-year probationary period. He also has to stay away from the victim, and attend 3 AA meetings per week for those 2 years.

If he doesn't comply with the judge's terms, he'd have to serve out a year in jail. If he does ... he can avoid that. Oh, and he's also expected to register as a sex offender.

Hailey Baldwin has seemingly made Justin Bieber the happiest we've seen him in a while ... so much so, JB's back to chatting up fans and paps.

Justin and Hailey were leaving dinner at Cecconi's Tuesday night in Brooklyn walking arm-in-arm ... and getting bombarded by fans and photogs. Hailey made for a quick escape into their waiting car, but Biebs was super friendly -- talking to fans, photogs -- and even taking a trip down memory lane with some locals.

The two, who dated briefly in 2015, were first spotted back together in Miami over the weekend. Looks like they can't quit each other now that their romance has moved to the Big Apple.

It's cool though ... we like this Justin a lot more.

Whatever Nick Jonas has going with Priyanka Chopra appears to be the real deal, because she was his date for a wedding, and not just any wedding -- it was a family affair.

The youngest JoBro and Priyanka were arm-in-arm at his cousin's wedding near Atlantic City over the weekend. She was draped in a gold dress, and Nick was suited and booted ... but no socks with his white sneakers. So chic.

While they haven't made any official announcement ... all the "new couple" signs are there. They even traveled together for the wedding -- we got shots of them arriving at JFK airport.

We're told Nick introduced Priyanka to his older brother, Kevin, and his wife, Danielle. Yeah, ya know it's beyond just banging when family meet-and-greets are going down.

Blake Griffin was Mali-boo'd up with his new girl on Sunday ... ditching his shirt for a cuddly walk together in Malibu.

The Detroit Pistons superstar and Francesca Aiello -- founder of Frankies Bikinis -- seem to be inseparable since they were spotted sucking face in his Land Rover on Saturday.

There was more of the good stuff during their quality time on Sunday ... with the 2 sharing a smooch after getting back to Blake's car.

23-year-old Aiello is the first girl Blake's been photographed out in public with since his split with Kendall Jenner ... but, by the looks of it, he ain't thinkin' about her anymore.

FYI -- Aiello's a Malibu native ... so no word on whether she's gearing up for a cold winter in Detroit or if it's just a little summer fling.

Either way ... good for these guys.

Justin Bieber and Hailey Baldwin partied like it was 2015 ... looking very much like a couple turning up all over Miami.

The Biebs and Hailey were spotted hanging out down in M-I-A on Sunday ... first hitting up a church conference before chowin' down at the ritzy Casa Tua, and then hitting up LIV Nightclub at Fontainebleau.

Our sources say Justin and Hailey walked in together around 1 AM ... where they hung out on a VIP balcony, held hands and danced together. They were definitely not trying to keep things on the DL ... showing plenty of PDA for all to see.

Justin goofed around a bit too ... busting out the Floss dance as the crowd cheered him on.

We're told Hailey and Justin left the club around 3 AM holding hands.

Olivia Culpo and Danny Amendola just can't quit each other, it seems -- they were spotted back together over the weekend, showing off major PDA ... TMZ has learned.

The recently broken up couple were very much not so at a friend's wedding Saturday in Houston, where we're told Danny was in the wedding party. Sources tell us Olivia came as Danny's date, and that they were doing lots of kissing, hugging, and hand-holding.

Keep in mind ... they split up less than 3 months ago. Olivia told Access Hollywood in March that the two had in fact gone their separate ways, and that it was fresh and hard for her to talk about. Danny was on a similar tip a few days later, offering no comment.

It appears Olivia tried the whole single thing out for a minute -- she's been spotted out on the town with her girlfriends on a number of occasions since the break up. And we're guessing Danny did the same on his end as well.

Nick Jonas and Priyanka Chopra either don't care if people know they're banging ... or they're just really awful at hiding it.

Nick and the "Quantico" star arrived together at JFK on Friday headed off to who-knows-where -- but, one thing's for sure, this is a damn good looking couple ... even if they won't admit it.

Dating rumors started last year when they arrived together at the 2017 Met Gala, but she brushed it off ... claiming they were only posing together because they were wearing the same designer.

They also hit up a Dodger game together just a couple weeks ago.

Maybe they're rocking the same designer again as they jet off -- but something tells us they're whispering something hotter than fashion tips to each other.

With Kendall Jenner apparently out of the picture, Ben Simmons MIGHT be trying to rekindle things with Tinashe ... because the two hit the same nightclub on Thursday.

The 21-year-old Philadelphia 76ers star and the 25-year-old singer both hit up Poppy nightclub in West Hollywood ... and left right around the same time.

Ben left solo at 1:37 AM on Friday morning and Tinashe left about 20 minutes later at 1:56 AM.

The two had dated for a couple of months before recently splitting -- Ben was seen out a short time later going on dates with Kendall.

But, Kendall was sucking face with Anwar Hadid in New York City earlier this week -- a sign it's probably over with Ben -- and now, he coincidentally shows up at the same club as his ex?

Fitting that Lindsey Vonn and P.K. Subban finally made their long-rumored coupling Insta official in Smashville Wednesday night, isn't it??

There have been rumors about the two for months ... but Vonn and the NHL star finally publicly confirmed their relationship last night ... hitting the red carpet together at the CMT Music Awards.

The two have been spotted hangin' out a lot recently ... taking in a Red Sox game and a Celtics playoff game last month.

They also hit business classes together at Harvard last week ... and Vonn was at one of P.K.'s playoff games last month in Nashville too.

But, they've successfully avoided taking a coupley photo until Wednesday night, when Vonn made sure to caption their selfie with a yellow heart.

Maybe it was the Keith Urban love songs that did it??

The only rocks Scott Disick and Sofia Richie's relationship is on are the ones on the beach in Malibu, because that's where they stepped out to show the world they're still going strong.

The couple hit up Nobu Monday for lunch. Definitely for the food, and also for the cameras. It's where ya go when you wanna be seen ... together. Remember, Scott himself made it seem they were dunzo -- we know he was telling people last week at Kanye's party he's a single man. Plus, he was photographed getting close to a mystery woman.

We broke the story ... Sofia wasn't happy about the incident, but she's basically over it. Proof positive -- they left Nobu together in his drop top Rolls.

Nothing says we're back on like make-up sushi and sashimi.

Sofia Richie and Scott Disick aren't over yet -- despite multiple reports saying otherwise, and a photo of Scott cozying up with another chick last week ... TMZ has learned.

Sources close to the couple tell us Sofia and Scott have not broken up, and are still very much together -- contrary to what other outlets are reporting ... that they'd supposedly split.

We're told Sofia certainly wasn't happy with the photo of Scott getting handsy with a mystery chick at Kanye's album listening party Thursday night in Wyoming -- but she hasn't pulled the plug on their relationship. As for Scott and that girl ... they're just pals.

Sources say Scott has known the woman for years, and that holding her at the party was nothing sexual ... and only lasted a few minutes. They also did not go home together. Regarding him telling people at the party he was single ... we're told that was the booze talking.

Long story short ... Scott and Sofia are still an item. So, don't count 'em out quite yet.
