Victoria Beckham, Eva Longoria Get Handsy At 'Vanity Fair' Party (PHOTOS)

We knew Victoria Beckham and Eva Longoria were close... but we didn't know they were grab-each others'-boobs close.

The British designer and her Hollywood pal had a Girl's Night Out in honor of The Eva Longoria Foundation, partying it up at Beso in Los Angeles. Sponsored by Chrysler and Vanity Fair, the fete was also attended by Kate Beckinsale (stunning in pink Alexander McQueen), Serena and Venus Williams and Vanity Fair publisher Edward Menicheschi.

While the guests were technically there to honor Eva's foundation, which raises awareness of children's health issues and problems affecting the Latino community, they definitely took the time to let loose and relax (after all, New York and London fashion weeks are finally over!).

Beckham happily tweeted the night away, describing her slim blue and black Victoria Beckham dress as her "favourite dress from AW12!" and posting pics of Eva and Kate with the caption, "Night out with the girls!"

But Eva, who was wearing a neckline so wide and plunging that we're shocked the entire night wasn't a wardrobe malfunction, had the cutest photo of all. She tweeted, "My beautiful girl @victoriabeckham supporting me @vanityfair" with a pic of Beckham's hands wrapped loving around her chest.

Because what are friends for if not for holding your boobies in your dress?

Check out the stylish stars (and BFFs) below. What do you think of Eva and Victoria's outfits?
