Dating

The teenager Casey Affleck watched over in this year's Oscar-nominated "Manchester by the Sea" had 2 girlfriends in the film ... but uncertain if that translates to real life.

We got Lucas Hedges -- who was nominated for Best Supporting Actor -- who tells our photog he can't really measure his love life in the wake of his hit movie quite yet. Something about how he's not a normal 20-year-old anymore ... whodathunkit?

He also speaks to the controversy over Casey winning Best Actor, despite being accused of sexual harassment by 2 women a few years ago. Sounds like Lucas has his back.

J Lo made it official -- she and A-Rod are banging, and she let the cat out of the bag by posting a pic with him ... possibly in bed.

She pulled the ole post and delete Sunday ... briefly putting the pic on her Instagram story. A-Rod's face is covered but that's him playfully palming her head. They were spotted together in the Bahamas this weekend on a romantic getaway.

Drake who?

Good news for 5 Seconds of Summer fans ... drummer Ashton Irwin might still be on the market.

We got Ashton leaving Delilah Saturday and asked him about the trolls who lit up his Instagram account after he posted a photo with YouTube star Alex Losey.

If you listen closely, Ashton gives fans carte blanche to keep hatin'.

It's a GREAT offseason for NY Giants wide receiver Sterling Shepard -- who's on a crazy trip to Africa with his model GF, Chanel Iman ... and the pictures are fire.

The Sphinx ... Morocco ... Zambia ... Tanzania ... the couple is hittin' all the dope spots.

They even had a run-in with Will Smith!!

It's good to be rich.

It's not often people turn down a chance to knock up a supermodel ... but NFL star Julian Edelman told Adriana Lima he's not ready for more kids and that was one of the main reasons they split.

Rae Sremmurd's Swae Lee isn't giving up on dating Malia Obama, and now he has a very specific plan to sweep her off her feet -- but he knows he'll have to get through Barack first.

The "Black Beatles" rapper was at LAX talking about his dream collabs -- in music and with Malia. Swae made a plea to us a few months ago for the then-First Daughter to holla at him, and it's clear he's been thinking about it ever since.

Swae broke down every detail of their first date, and he's already on cloud nine.

NBA star Chandler Parsons has a big fan in Bella Thorne ... they're not only going to see movies together, they also shared a kiss in Mexico.

Selena Gomez staked her claim on The Weeknd with a serious this-is-MY-bf kiss on his cheek ... which we're sure had nothing to do with you-know-who being in town too.

Selena packed on the PDA Tuesday after his concert in Paris. But the "Starboy" singer was also performing at Wednesday night's H&M fashion show, where his ex, Bella Hadid, was doing her model thing.

Potentially messy? Sure. But Weeknd belted out "Nothing Without You" as Bella and Gigi Hadid strutted, and there was no drama apparent to the naked eye.

For the record, Selena was NOT at the H&M show.

Nick Jonas knows a thing or two about winning a woman's heart ... and, apparently, the bowling date is right up his alley.

We got Nick Tuesday at LAX, and while he was fairly tight-lipped for a lot of questions ... he did open up for some crucial dating advice and insight into his game, love and otherwise.

Sounds like those Jonas boys can't miss.

Justin Bieber is in a race to the bottom ... but at least now he's got some attractive company.

Bieber took a 1-on-1 hike with his model friend, Ashley Moore, who seemed down to get physical with him in a friendly competition running on a canyon trail.

If there's one thing we know about Bieber ... he tends to open up in the wilderness. Bodes well for Ashley. Plus they've hung out before -- couple years ago at a Clippers game -- so, seems like they've got a connection.

If The Weeknd has any menage a trois fantasies ... this would be the time to let Selena Gomez know -- the couple's in Paris, and staying just a few minutes away from his ex, Bella Hadid.

Selena and The Weeknd were spotted chilling at their hotel -- which happens to be a convenient Parisian stroll away from the one where Bella's staying.

He's in town for a tour, and Bella's there for fashion stuff. We're guessing Selena's there because, well ... maybe she knew Bella was gonna be there.

Rachel Lindsay doesn't care what kind of men step in for her season of "The Bachelorette" -- black, white, it's all good ... but she does want to see a mix.

We got Rachel at Floyd Mayweather's weekend birthday bash inside the J.W. Marriott, and she told us she isn't looking to overcompensate in diversity for her guys just 'cause she's the 1st black 'Bachelorette.'

That's not to say she does want to see a range of color in her contestants, whom she apparently doesn't have all that much of a choice in picking. She did drop a hint though as to what kind of man COULD win her heart.

A rep for Norman tells us the two are just friends and did not take a trip together.

Diane Kruger and Norman Reedus just moved past rumored fling status to romantic road trip couple.

We got these shots of the celebs in NYC allegedly returning Thursday from a getaway in his fancy sports car. Diane was all smiles as Norman unloaded the whip. Who knew Porsches had that kinda cargo space?!

Chris Brown was partying Thursday night with a Karrueche look-alike, but he was in no mood to talk about the real Karrueche's claim he brutalized her and threatened to kill her.

Chandler Parsons is NOT in an official relationship with reality star Savannah Chrisley, despite reports to the contrary -- they're just "good friends."

Here's the deal ... people went crazy after the "Chrisley Knows Best" star appeared on "Access Hollywood Live" on Thursday and talked about Chandler when asked about her "new boy."

Her father -- who also appeared on the show -- said he's met (and likes) Chandler but expressed concern about his daughter dating an NBA player.

Well, dad ... don't worry.

Sources close to the NBA star tell us they've definitely hung out -- but they ain't exactly boyfriend/girlfriend.

"Savannah and Chandler are just close friends," one extremely connected source tells us.

We know Justin Bieber's pissed at The Weeknd ... but who knew it was literal?

Biebs was cruisin' along Wednesday in WeHo in $400 sweats that will now resell on eBay for either a lot more or a lot less.

His aim on the basketball court clearly doesn't translate.

Even Justin thinks the pic is a wicked pissah ...
