Jennifer Lawrence looks relieved after news broke that she and Chris Martin have called it quits.

X17 snapped these EXCLUSIVE pix just a half hour ago, as the Oscar winner pumped her own gas and shot our photographers a big smile when she headed back into her Cadillac.

Earlier today, news hit that the "it" couple split after dating since June. The Hunger Games girly supported the Coldplay singer last month at the iHeart Radio concert in Las Vegas and again this month, when his band played a private gig in downtown LA.

As our photographer approached Lawrence today, he asked if she was doing okay after the breakup and that's when she gave him a big smile. Our photog told us, "Jen was totally relaxed and happy. She seemed more calm than when she's with Chris. She wasn't anxious and didn't have that nervous look. She kind of laughed when I asked her about the breakup. It looked like she was relieved."

The 24-year-old actress is the one who broke it off with Chris, People.com reports. Looks like the newly single star is doing anything but moping around -- seems like she definitely did the dumping!

We can't wait to hear some new Coldplay songs about another lost love!

Good thing her rumored new boo lives in the 'Bu too!

Miranda Kerr arrived at an escrow office in Calabasas today to finalize the purchase of her new $2.15 million Malibu home, and we bet she was rushing to finish the paperwork so she has a place of her own to retreat to after steamy nights at Steven Bing's abode!

Over the weekend, the supermodel was spotted arriving at the billionaire's beach house with son Flynn, and she went out of her way to avoid being photographed, which leads us to believe she was trying to keep the new romance under wraps. That could also be because she's still dating media mogul James Packer, but after seeing him partying with Leonardo DiCaprio and a bevy of scantily clad ladies on Sautrday, we don't know what to think. Until we know the real story, we're just going to assume the two uber wealthy businessmen are fighting over the Victoria's Secret stunner!

We were just beginning to get used to them! Hunger Games actress Jennifer Lawrence and Coldplay singer Chris Martin have split, People reports.

Reps for both stars have yet to comment on the break up.

The 24-year-old Oscar winner started dating in August, after Martin's split with wife Gwyneth Paltrow and Lawrence's break up from boyfriend Nicholas Hoult.

We are definitely surprised to hear of the split -- their relationship seemed to be growing and getting more serious! Last month, JLaw flew to Las Vegas to see Chris Martin perform at the iHeartRadio music festival and earlier this month, the actress attended one of Martin's Los Angeles concerts.

The two were together as recently as Oct. 21. Maybe Lawrence got sick of all his "friendly" dinners with Gwynnie?!

An Australian billionaire hanging out with a bunch of scantily clad ladies in costume?! Sounds like a movie script! But leave it to world-famous playboy Leonardo DiCaprio to set up a night of debauchery between himself, 47-year-old media mogul James Packer, Brody Jenner's 22-year--old ex girlfriend Bryana Holly (who dressed as a slutty Grecian goddess), some nameless slutty Wonder Woman, and a few more slutty sluts.

Uhh we wonder what antics this group got up to?! We're sure these well-meaning rich dudes and these classy ladies just played a good round of wholesome checkers together or gathered some canned goods to bring to a food bank. Yeah ... right ...

After enjoying a Halloween-themed dinner at Nobu on Saturday, Leonardo, Steve, Brody Jenner's and the other women climbed into DiCaprio and Packer's car to continue their night of fun, making their way to Hollywood nightclub, Blue Collar.

We were a little surprised to see Packer hobnobbing with an A-lister like Leo, but it turns out that Packer has just formed his own production company, RatPac Entertainment, with super producer Brett Ratner.

Umm last we heard Packer, who is the third richest person in Australia and worth an estimated $7.9 billion, was dating Orlando Bloom's ex, Miranda Kerr. If they are still together -- we can't imagine the supermodel would be down with this sexy party. However, Miranda's been off spending alone with millionaire Steve Bing, who is Elisabeth Hurley's baby daddy. Over the weekend, we caught Miranda and Steve hanging out at his home in Malibu.

Those exclusive photos and more coming tomorrow …

OMG! Gwen Stefani and Gavin Rossdale's family is sooooo cute!

Gwen and Gavin went for a stroll with her son Zuma, infant Apollo on Sunday in Studio City. Zuma looked like he was having a kooky time, hamming it up while walking with his rockstar mama.

We loved seeing Gavin take on daddy duty as he held his 8-month-old son close to him. It's too precious for words!

For the family outing, Gwen wore jeans, a black shirt and some eye-catching orange kicks. The Bush frontman donned an equally casual look of a white T-shirt, jeans and Nikes. The rockin' dude opted to keep out of the sun with a fisherman's hat. We couldn't help but notice that baby Apollo's onesie had trompe l'oeil checker suspenders on it -- just like mommy back in the day. Adorbs!

Even off duty, these proud parents know how to look good!

No, it's not a sweet, sweet fantasy! That really is Mariah Carey performing in Taiwan for the first time in 16 years! The big-voiced singer turned up the volume for the people of Taiwan when she performed at the Taipei World Trade Center Nangang Exhibition Hall on Sunday night, which is the first time she's performed in the country since 1998.

According to the Taipei Times, the newly single songstress got a whopping $900,000 for the concert. With a paycheck like that -- why didn't she come sooner?!

For the big event, Mariah rewore the headline-making metallic dress that she donned during a performance in Shanghai, China, exactly a week before. The 45-year-old caused quite the commotion the week before when she wore the eye-catching dress and her slit exposed a whole lotta leg in Shanghai. Only for last night's performance, Ms. Carey opted for black tights to save herself from another wardrobe malfunction. Good call!

Carey last serenaded the country in 1998 during her Butterfly World Tour. Mariah released her 14th album, Me. I Am Mariah... The Elusive Chanteuse in May.

There seems to be some lingering beef!

Snoop Dogg arrived at LAX yesterday and the rapper was peppered with questions about his feud with Iggy Azalea, but instead of responding, he chose to sing Big Sean's "I Don't F**k With You" and let that be his statement! Considering the song is about a "stupid a** ho" we can gather how he feels about the songstress…

These two just need to accept the fact they hate each other and keep their mouths shut!

Back to where it all began!

Kim Kardashian and husband Kanye West relived memories on Sunday by attending the Giants World Series game at AT&T park, which is where the rapper elaborately proposed to the reality star a year ago.

The visit marks the first time the A-list couple has been back since Yeezy popped the question, and the Keeping Up with the Kardashian star shared several snapshots of the occasion on her Instagram account. "#DateNight #WorldSeries #IHaventBeenBackHereSinceISaidYes," she captioned one of the photos. Another pic shows the pair posing in a box with baseball legend Barry Bonds.

The duo have had quite the whirlwind weekend! Kimmy K hosted her birthday bash at TAO in Las Vegas on Friday, then they flew back to L.A. Saturday to attend family friend Scott Sartiano's wedding before catching a late night movie at The Grove. These two are nonstop!
