Gwyneth Paltrow at Obama Fundraiser in London

Gwyneth Paltrow slipped into a sexy white Tom Ford dress for a special event in London this evening. She was one of the famous faces, including her Emilia Wickstead-clad pal Cameron Diaz, Tom Ford himself and Anna Wintour, at the Obama Victory Fund dinner held at Mark's Club.

Gwyneth played cohost for the occasion, which came just one day after her pal Beyoncé Knowles held her own political function. Beyoncé and Jay-Z hosted a party at Jay-Z's 40/40 Club in support of President Obama's reelection campaign last night. Michelle Obama wasn't able to attend either event, but she is answering your questions on PopSugar in the coming weeks — make sure to submit your questions to the First Lady now!
