LA's Hottest Turn Out In Support Of Stella And Paul McCartney

A pregnant Reese Witherspoon, the London-based Gwyneth Paltrow, the reclusive Kristen Stewart and the super-busy supermodel mom Miranda Kerr all put their schedules on hold to support their favorite fashion designer Stella McCartney and her dad Paul at a party in her Beverly Hills boutique Friday night.

So just how was this father-daughter duo teaming up? Stella hosted a party to celebrate dad Paul's new music video for My Valentine. The black-and-white mini-film, directed by Paul himself, was shown in three versions -- one staring Johnny Depp, one staring Natalie Portman and another that merged the two together.

McCartney's BFF, Gwyneth Paltrow stunned in Stella's vegan booties, jeans and a tuxedo blazer. She met up with hubby Chris Martin inside. Coldplay's playing at Coachella this weekend, so the couple is taking a break from London to be on the Left Coast.

Reese covered her baby bump in a stunning black dress and sky-high black pumps. Meanwhile, Miranda wore the "it" dress of the spring -- the Stella swirl dress in black with an off-white blazer.

But beyond the fashion, it was the film that brought these A-listers together. Check out Paul's video -- it's a winner!
