It may seem more London than Hollywood, but stars turned out in full force over the weekend to don fancy dress, sip champagne and watch a polo match ... some even bringing along their entire families!

The 3rd Annual Veuve Clicquot Polo Classic went down at Will Rogers State Historic Park in the posh L.A. suburb of Pacific Palisades on Saturday.

Mandy Moore, Ellen Pompeo, Ali Larter and Selma Blair were a few of the celebs who attended the event, held by the luxe French champagne brand.

Other stars like Rebecca Romijn and Jerry O'Connell, Alessandra Ambrosio, and Rachel Zoe chose to make it a family affair, bringing along their adorable kids for a day of fun in the sun!
