He's definitely got a spring in his step!

Chris Martin decided to go barefoot on an errand run in Malibu over the weekend, and the singer looked so happy and laid back that we have to wonder if his cheerful demeanor is due to a new romance? Reports surfaced that the Coldplay rocker and Kate Hudson were dating after they were spotted grabbing dinner with their children last week, and we can totally see these two as a couple!

The Almost Famous actress better get ready for the cat fights that will inevitable ensue if she continues to pursue a relationship with the British rocker, because his ex-wife Gwyneth Paltrow is "livid" and his on-off girlfriend Jennifer Lawrence isn't going to back down without a fight.

"Since Kate and Matt Bellamy split last fall, she’s been clingy with Chris, calling him all the time to suggest get-togethers under the guise of setting up play dates for the kids — which is exactly how the beach day and dinner date came to be," an insider told In Touch. "[Jen's] not going to just let this happen. She’s invested a lot of time into making this relationship work," the source added about the Oscar winner.

Ladies, he's not even divorced from the Goop queen yet!

After attending the premiere of Home in a demure pink gown on Sunday afternoon, Rihanna went for a much more risque ensemble when dined at Giorgio Baldi that night. Seeing as Home is an animated flick with a PG rating from the MPAA, her tame red carpet look makes total sense ... but we can't believe how much cleavage she flashed just a few hours later!

Home is about an alien (voiced by Jim Parsons) who lands on Earth and makes friends with Tip (voiced by RiRi), and Jennifer Lopez and Steve Martin also star in the film. RiRi previously tried her hand at acting in the big screen disaster Battleship, but after getting a peek at the trailer for Home, it looks like she may have found her niche with VO work! Not like she needs the extra dough -- she's worth an estimated $120 million -- but it's good to branch out!

What an odd group!

Mariah Carey got all dolled up to dine at Craig's at Hollywood, and the singer's dates for the evening were Courtney Love and Brett Ratner. How do they all know each other? We would love to be a fly on the wall to hear their conversations!

The songstress seems to be doing ok since her split from husband Nick Cannon, but she can't be pleased that the father of her children has already moved on with model Jessica White. "Jessica fully respected Nick's relationship and would never get in between anything with them. When Nick was going through his breakup, Jessica was there for him as a friend. They been spending lots of time together and Nick really enjoys Jessica's free spirit and easy-going attitude for life," a source dished to E! News.

Mimi needs a new man!

LeAnn Rimes and husband Eddie Cibrian went to his sons' soccer game on Sunday, and when the two weren't cheering on Mason and Jake, they were all over each other! Hey, if they've been married for 3 years and things are still this steamy, props to them...

LeAnn wore a beautiful maxi dress, and we know we've been on bump watch with the country crooner for a while, we can't help but wonder if she might be hiding something? After all, she revealed on the couple's now-cancelled reality show that she was dying to have kids and the series chronicled their fertility struggles, so it wouldn't be impossible. Lele has always embraced her role as a "bonus mom," and after the game she posted an adorable snapshot of Eddie and his youngest son and wrote, "Sweet Daddy Love! #Sundaysoccer
This kiddo kicked butt playing goalie. I think he found his golden position ⚽️ #prouddadandstepmom." Awww ... We know it's only a matter of time before the two have their own child!

And if it's not pregnancy rumors, it's divorce rumors! Earlier this month a report surfaced online that LeAnn had installed surveillance cameras in the couple's home to catch Eddie cheating, but after seeing these pics of them together, we're not really buying it ... are you?

Halle Berry and husband Olivier Martinez ran errands with their 19-month-old son Maceo over the weekend, and we can't believe how much the celebritot has grown!

Despite the fact that Maceo was a bit wiggly, Halle and her hubby were all smiles as they strolled through the parking lot. Olivier is notorious for testy with photographers, but it certainly seems to us like fatherhood has mellowed him out -- we've never seen him this mushy before!

Aside from daddy duty and a little bit of TV work, we're not sure what projects Olivier is working on these days, but Halle has been kicking butt as astronaut Molly Woods on the CBS series Extant. The show's ratings haven't been amazing, but it did get picked up for a second season ... and Halle's next film, Kidnap, is set to hit theaters later this year. She's been a busy mama!

So sad!

Dee Snider returned from vacation early after the untimely death of his Twisted Sister bandmate A.J. Pero, who passed away March 20 while on tour with his other band Adrenaline Mob, and the legendary front man spoke to X17online exclusively about his grief and plans to attend his friend's funeral in NYC later this week.

"Coming home to sad news. My drummer died of a heart attack yesterday. A.J. Pero, great drummer, legendary drummer. He had a great outpouring; I'm heading to the funeral in New York later this week. Very sad," the rocker told our videographer.

"He had a massive heart attack in his sleep and we lost him. He's the first member of the band to die, and it's very sad. We will continue to play for his family, because his family will benefit financially. Very heartbroken," he added.

"Today, I lost a brother. Anthony Jude Pero passed away. A.J. was the final piece in a band that would become an international sensation and one of the greatest live rock acts to ever hit the stage. His sledgehammer assault on the drums helped drive Twisted Sister and me to greatness and inspired me to rock every single show. My heart breaks knowing I will never feel the power of his beat behind me, or turn to see his face smiling broadly from the sheer joy he got from doing what he loved. I will always remember that smile. R.I.P., my friend," Snider said in a statement to Rolling Stone after the news broke.

Just tragic!

WHOA!!!!!!

Rob Kardashian's clearly losing it. Whether you like Kim Kardashian or not, she's certainly not equivalent to the murderous psychopath Amy Dunne in Gone Girl. What the heck's Rob doing??!!

The 28 year-old just posted this still from the movie, with the caption: "This is my sister Kim, the b**** from Gone Girl."

Sis Khloe just spoke about her troubled brother recently, to Wonderwall, saying of Rob, "I just feel, especially over the last year, Rob has become very introverted and has a kind of social anxiety."

He just un-followed his entire family on Instagram and he had previously deleted all his posts. Now he's got 2.7 million followers and the only thing on his account is this. Uh ... is Rob on the verge of a nervous breakdown?

Jennifer Lawrence hit the town in New York, on Saturday, as her ex, Chris Martin, spends time with Kate Hudson back in Malibu.

The Hunger Games star celebrated the VOD release of her new film Serena at the top of the Belvedere Hotel with third-time co-star Bradley Cooper. The pair shared the big screen in 2012's Silver Linings Playbook, then again in 2013 for American Hustle. Lawrence says of the repeat on-screen pairing, "Honestly, it's just happenstance. We both got cast in Silver Linings, and she was going to this other movie and the role was open and so that worked out."

Now seems like the perfect time for the on-screen loves to seek solace in each other off-screen, as it was reported last week, Cooper and long-time love Suki Waterhouse split. Could that, and Lawrence's ex Chris Martin spending time with another blonde beauty, Kate Hudson, drive them into each other's arms?!
