Justin Bieber and Selena Gomez hung out in his Calabasas neighborhood on Thursday, and on Friday Biebs Instagrammed this shot of the two hugging and wrote, "Love the way you look at me." If this isn't a sign that the two are back on, we don't know what is! Then again, they're so hot and cold, we can't even keep up with them...

The young stars began dating in 2010 and made their first public appearance in early 2011 at an Oscars bash, but by November of 2012 they had parted ways, citing their busy schedules as the main reason for the breakup. However, less than two months after that, the duo started hanging out again, and they even planned a romantic vacay to Mexico. Of course, that never happened as the lovebirds got into yet another squabble, but in April she flew to Oslo to surprise Justin and he posted a picture of them cuddling. Though that didn't last, there was another shot of the two posted in July, so they can never seem to go more than a few months without hooking back up.

Wonder if Bieber's recent interview with Power 106's Big Boy had anything to do with the two getting back together? The 19-year-old singer introduced his hit song "All That Matters" on the radio show, and he confirmed that it was about Selena. "It was written when I was in a great place in my relationship and at that time she was all that mattered," he said, adding that he was very much in love with her. "[The breakup] affected us, especially when we are in front of so many people -- it's such a public thing -- it's hard for the both of us. But you know, she's a great woman, I love her to this day."

I guess he's finally ready to come and get it! But will 2014 be the year that they stay together?

Make that Kaley Cuoco Sweeting -- girlfriend has already changed her Twitter handle to her married name!

On Friday Kaley and her hubby Ryan Sweeting went shopping at Barneys New York in Beverly Hills, and we're not sure when the lovebirds are going on a honeymoon, but they were indulging in some retail therapy in the meantime.

The duo tied the knot on New Year's Eve at Hummingbird Nest Ranch in Malibu, and the event doubled as a fire and ice themed holiday bash. Cuoco and Sweeting exchanged vows in front of 150 guests around midnight, and the Big Bang Theory actress wore a pink Vera Wang gown. The newlyweds posted a handful of photos on Instagram, and in one Sweeting wrote that his "cheeks hurt from smiling so hard" and that it was the "best night in history." Awww!

Josh Duhamel ran errands in Los Angeles on Friday, and it's not that often that we see him without his adorable baby Axl!

Josh and Fergie had a mellow Christmas with their 5-month-old son, and it sounds like the parents couldn't be happier with the way things have turned out. Duhamel recently chatted with Life & Style and revealed that Axl has "brought us closer," and a source close to the couple added, “Fergie just want to stay in and spend time with her two men.”

Given how hot Josh is and how precious their son is, we can clearly see why!

Kylie Jenner and her pal Jordyn grabbed sushi from Sugarfish on Friday afternoon, and the 16-year-old reality TV starlet took advantage of the unseasonably warm weather and wore a very short skirt (though we think it might actually be a skort) with a white top and a plaid jacket.

And speaking of her look, she took to Keek to answer some fan questions about her ever-evolving style, specifically with regards to her hair. "I just feel like there was a lot of stress I needed to let go, so I chopped it off," Kylie said in one video. "I actually love my hair. I'm cutting more off tomorrow. I'm going a little lighter, because I feel like it. But I love my hair way better short."

So what's the stress about? Given her recent posts, it seems like Kylie is having some major boy drama, and while she won't say whether it's about Jaden Smith, she hasn't stopped posting Instagram selfies with cryptic captions! Just a few hours after X17 snapped these shots of Kylie, she posted the pic below and wrote, "I knew I loved him when I let him go la la la."

On Friday Simon Cowell and his pregnant girlfriend Lauren Silverman shared a sweet moment after the music mogul hit the waves to jet ski, and it looks like the lovebirds are having the time of their lives in St. Barth.

While Simon was busy playing in the waves, Lauren ate lunch and soaked up the sun on the deck of their massive yacht, and she showed off her growing belly in a printed one-piece swimsuit. It's been reported that Lauren is due to give birth sometime in February in New York, so this might be one of the last trips she goes on for a while!

“I went to see a scan today and it is just surreal,” Simon told The Times of London back in September when he saw a sonogram of their child for the first time. “You literally see this thing which is now alive moving around. I feel very paternal right now. So, I am very happy.” Aww!

Ke$ha has confirmed that she checked in to rehab for an eating disorder.

The 26-year-old singer said in a statement on Friday:

"I'm a crusader for being yourself and loving yourself, but I've found it hard to practice. I'll be unavailable for the next 30 days, seeking treatment for my eating disorder ... to learn to love myself again, exactly as I am."

Us Weekly reports that Ke$ha is at the Timberline Knolls rehab center in Illinois, which is the same place Demi Lovato completed treatment back in 2010.

Though Ke$ha has been honest about her body image issues over the years, this does come as a bit of a shock. On New Year's Day, the seemingly happy and healthy singer debuted the racy music video for her song "Dirty Love" music video, and shortly after that she tweeted, "Cheers to this year being the best year ever. 2014 gon be the year of truth and freedom."

Here's to hoping she gets all the help she needs ... get better K Money!

After sweating it out in skintight spandex, Kim Kardashian stopped by the salon for a manicure, and after that, Kim met up with beau Kanye West and spent some dough at Naimie's Beauty Center in Los Angeles.

Kim wore her highlighted locks up in a bun, and though she's been rocking the blonde for a while, it sounds like she's itching to return to her dark roots. When a fan asked how long she was planning on staying blonde on Mobio last week, Kim admitted that she wants to go back to brunette. "I had the urge to go dark today when I was at the salon but I finally got the color blonde so good, I want to wait a little longer," she said. "I go back and forth all the time on what color I want my hair.”

Oh and you ever wonder why Kanye always walks behind his baby mama?

She may have married Ryan Sweeting on New Year's Eve, but Kaley Cuoco spent some time with her four-legged loves on Thursday afternoon at the barn in Los Angeles.

Kaley has been riding for years, and despite a nasty fall in 2010 that left her with a broken leg, she got back in the saddle a year later. Kaley recounted the story to Ellen DeGeneres a few years ago and revealed that the fall initially wasn't that bad (her horse spooked and she fell off), but the animal then tried to jump over her, at which point his hoof landed on her lower leg and essentially snapped it in half. "I looked, and I’m like, wow, my foot’s facing me … And I was like, that’s not normal," she told Ellen. Yikes!

Kaley was back in the show ring this fall competing in the jumpers with at least one of her horses, so we're happy that she seems to have put the terrifying accident behind her!
