We never would have guessed that these two would be an item!

Jaden Smith, 14, and Kylie Jenner, 15, are dating, according to Us Magazine. "It's new, but they've been friends forever," a source tells the mag.

On Sunday Jaden and Kylie were spotted on a lunch date at Caffe Nero in London's Piccadilly Square, but prior to that Jaden was kicking it with Justin Bieber, who celebrated his 19th birthday on Friday at Cirque du Soir.

Bieber's entourage apparently got into a squabble with club security because Jaden is underage (the drinking age in the U.K. is 18), and while Bieber denied that was an issue, a source tells the mag that it definitely "caused problems." After the argument, Bieber was photographed stomping around in the street without his shirt on, and a few hours later he tweeted, "worst birthday."

Biebs later added, "Sometimes u just wanna vent and not be quiet. I love my fans though. Just gonna chill with friends. London shows this week. It ain't always easy but is what it is. Gonna stay focused." Hopefully he's not mad at Jaden!

Over the weekend Jennifer Garner hit the gym in Santa Monica, and while she wore different clothes, her outfits were nearly identical on Saturday and Sunday! Jen was busting her butt to get in shape for awards season, but now that it's over, it looks like she's trying to slim down even more. Good for her!

Meanwhile, hubby Ben Affleck was busy going on a coffee run with his brother Casey:



Hopefully his little brother doesn't mind being the one who picks up the 'Bucks!

When is the wedding lovebirds?!

Kat Von D and fiance Deadmau5 held tight to each other as they walked through West Hollywood on their way to grab a bite over the weekend, and although they broke up briefly a couple months back, they seem to be going strong and look more in love than ever!

The edgy tattoo artist wore a black tank and biker boots, but what really stood out was her black diamond engagement ring!

The L.A. Ink star has never looked this happy before, so we're pretty confident these two will end up making it down the aisle!

Rough life!

Selena Gomez and a female pal indulged a in little retail therapy in Beverly Hills over the weekend, and the Spring Breakers actress was sweet enough to stop and buy a box of Girl Scout Cookies from a young fan.

Spending her hard-earned cash must have given her a sugar craving!

In fact, Justin Bieber's ex-girlfriend has been splurging on junk food a lot since their break-up. Just last month, we caught the Wizards of Waverly Place star hitting a MacDonald's drive-thru followed by a trip to Starbucks.

Treating yourself to a cookie when you've just broken up with the world's biggest pop star is completely understandable!

After grabbing a bite to eat and attending the Kenzo show on Sunday for Paris Fashion Week, we spotted Jessica Alba and her adorable daughter Honor shopping at Zadig & Voltaire and Gerard Darel. Looks like mama stocked up on goodies for herself and her oldest child!

Hubby Cash Warren is in Los Angeles with 19-month-old Haven, and as soon as she arrived on Friday, Jess tweeted the pic below and wrote, "Bonjour #Paris #girls-trip! W @lauren_andersen & my big girl!"

These two sure know how to relax!

Mila Kunis and boyfriend Ashton Kutcher decided to spend their Sunday kicking back at the foot spa in L.A., and this isn't the first time the couple have gotten their tootsies worked on together!

The brunette beauty kept it classic in jeans and a white button down, while her Two and a Half Men beau channeled his inner hippie in Birkenstocks!

Later on in the evening, the pair went for a curry dinner at The Great India restaurant in Studio City before heading home and making it an early night.

They seem to be inseparable lately, and we wouldn't be surprised if Ashton puts a ring on it soon!

Kim Kardashian and baby daddy Kanye West were snapped out after dark in Paris on Sunday evening, and you know these two coordinated with their black and white suits! "Last nights Givenchy look. #Black&White #tux #RiccardoTisci," Kim tweeted. Earlier in the day she attended the Givenchy show, so perhaps she drew some inspiration from that?

And speaking of black and white, the rest of the sexy photos from Kimye's L’Officiel Hommes cover have hit the web, and they're quite sexy!



These two really can't keep their hands off of each other! But when will Yeezy propose?

We've been waiting for an opportunity to see these little ones!

Anna Paquin enjoyed family day in her Venice neighborhood on Sunday, and the True Blood actress gave us our first look at her adorable twins, who were born in September of last year.

Accompanied by her husband Stephen Moyer and her stepdaughter Lilac, the Oscar winner popped into a local toy store to pick up some goodies for her tots. She cradled her little boy in her arms and planted sweet kisses on him while they did some shopping, while her little girl was slightly sleepier than her brother and relaxed in the stroller.

The couple have yet to release the names of their newest additions.

After a brief break to bond with their children, the pair are back to work filming the sixth season of True Blood.

Too cute!
