Dating

All signs point to Miley Cyrus and Liam Hemsworth becoming a couple again, and we've learned the romantic reunion has been in the works for months.

Sources from their inner circle tell us they weren't surprised to see the exes hanging together in Australia this weekend, but they've been back in each other's lives since the fall. We're told Miley's not using the bf label yet for Liam, but they're well beyond the friend zone.

Our sources say they've been in almost constant communication -- texting and FaceTiming -- and never really stopped loving each other, despite the break-up. She's been singing his praises to friends even more lately.

We're told Miley came through for him a few weeks ago ... watching Liam's dog, Dora, when he was out of town.

Jason Derulo and new gf Daphne Joy are certainly comfortable with each other, walking as one through LAX.

The two touched down on Saturday after a wild weekend celebrating the New Year in Miami. As you can see, Daphne, who has a kid with 50 Cent isn't afraid to pack on a little PDA ... touching Derulo's butt while they wait for their luggage.

You'll remember, Daphne first shot down reports they were banging back in November but it's safe to say those doubts are gone.

Justin Bieber is owning the obvious ... he's hooked up with Hailey Baldwin.

Justin posted this pic which tells the story we told you over the weekend ... they've been in St. Barts and not hiding their relationship at all ... making out at a fancy schmancy New Year's Eve party in front of hundreds.

Selena, Kourtney and maybe Kendall ...cover your eyes.

Justin Bieber and Hailey Baldwin aren't hiding their relationship ... at least around their closest 200 friends.

Justin and Hailey were making out for everyone to see at a New Year's Eve party thrown by Richie Akiva at a villa in St. Barts.

Akiva, a big-time nightclub guy, had a bunch of people over at his party, Justin performed and they were sucking face for everyone to see at the bar.

We're told this isn't the first time the two have locked lips.

Congrats to both.

It's official ... Miranda Lambert has bounced back, moving from country to R&B.

Anderson East left little to the imagination after posting this pic of cuddling with Blake Shelton's ex, captioning it, "The snuggle is real."

The 2 are in Aspen on holiday. BTW, he's 27 and she's 32.

Kendall Jenner and Harry Styles became extra familiar with each other on a luxury yacht in St. Barts.

The two were spotted Wednesday getting handsy after reports surfaced they'd been vacationing together in Anguilla the night before.

It's unclear if the two are "officially official" but judging by the pics, the 20-year-old supermodel and 21-year old pop star certainly have no problem packing on the PDA.

Word on the street is that The Weeknd and Bella Hadid called it quits -- not so.

Our sources who are closely connected to both of them say Bella wasn't with Weeknd over the weekend because she wanted to spend time with her mom Yolanda and sister Gigi.

Fact is ... everyone's telling us the relationship has never been one where they were inseparable. They've always spent a lot of time living their separate lives.

Maybe it's a mistake, or maybe it's intentional ... but Gwen Stefani has a new Twitter follower -- Miranda Lambert.

Maybe old feelings die hard, but Gwen's been tweeting a lot about Blake Shelton and places they go, and it seems Miranda's interested.

The twitter web is tangled for sure ... Gwen still follows Gavin Rossdale, Gavin follows Gwen, Miranda still follows Blake, and Blake follows Miranda.

Social media divorce is way harder than regular.

Caitlyn Jenner and son Burt got mistaken for boyfriend and girlfriend ... hilarious for sure, but it soon turned ugly.

Caitlyn and 37-year-old Burt Jenner went to lunch Monday in West L.A. when photogs jumped to the conclusion they were hooking up and peppered them with questions.

Check out the video. You see Caitlyn leave and Burt blocked one of the photogs so he couldn't follow her. When the photog gets out of his car -- presumably to confront Burt -- Caitlyn's son goes on the attack.

Master P's found a silver lining to all his marriage drama -- he's going to host and produce a relationship/sex talk show on Playboy Radio.

We found out P signed on the bunny to do a show called "Doin' Tha Most" -- and he'll be dishing advice about sex, love, and possibly marriage. It's an interesting hire since Master P's been locked in a messy divorce battle for nearly 2 years.

But you gotta figure after all court dates, spousal support battles and restraining orders ... he's probably learned plenty -- about what to do or NOT do.

Aubrey O'Day and PaulyD have defied the odds and are in what appears to be a real relationship, cemented by alcohol.

It seemed ridiculous when they hooked up on a reality show a month ago. It seemed like a momentary fling, but a month later she's travelling to his DJ gigs.

Pauly hosted Pool After Dark in Atlantic City over the weekend, and Aubrey was front and center.

Demi Lovato and Wilmer Valderrama are still going strong and they're happy to show it.

The couple's been together since 2010 when they met on the set of a PSA for Voto Latino. Lovato said they've been together ever since.

She brings 23 to his 35 and she's not shy about marriage ... she said she'll walk down the aisle for the asking ... she even has part of her wedding planned.

Pre-mazel tov!

That shirtless jogger who went viral because he's hot and looking for love, has something more than just great looks to offer -- he's a 24-year-old virgin.

Ethan Renoe tells TMZ he's been single since 2008, but all that's likely to change since he's been hit up by a couple thousand women after WGN posted the clip of Ethan for a run Sunday in Chicago in the rain ... without a shirt. As he explained, it was just too wet for a top.

Now the recent grad of Moody Bible Institute is getting flooded with offers. Ethan says he's serious about finding himself a woman, but says he's still going to wait for his honeymoon to tear up his v-card.

As for the rest of his dating profile -- Ethan's into photography, personal training, nannying, construction, teaching and, of course ... running topless in the rain.

Kate Gosselin is looking for love ... but first, they gotta be able to handle the 8 that go along with it.

Kate was out in NYC promoting her return to TLC with "Kate Plus 8" when she mused about the type of man she's looking for (HINT: basically the opposite of Jon)

Kourtney Kardashian made clear what TMZ has been telling you .... she's available.

Kourtney was out at The Nice Guy Friday with no Scott Disick in sight. As we reported, she's not getting back with Scott, although they're spending time together as parents of 3 kids.

She left the club late Friday night and made a beeline for the Montage in Bev Hills where Justin Bieber stays -- he was at the club as well. She left the hotel at 4 AM.

Her sister Kylie was hanging at Saks Fifth Ave Friday night ... sans Tyga. Although it seems weird, they're still together but often hang separately so as not to confuse their brands.

Justin Bieber is dating lots of chicks ... and he says he's not back with Selena -- but it sure seems he wants the option.

The Biebs posted this pic of him with S.G. back in the day ... it looks like 2013.

As for why he did it ... reports surfaced Selena was macking One Direction's Niall Horan at Jenna Dewan-Tatum's 35th BD party Friday night at Bootsy Bellows.

It's like Jake in "Brokeback," ... right?
