Maria Shriver, the wife of California governor Arnold Schwarzenegger, hosted a Women’s Conference at the Long Beach Convention Center in LA last night.

Maria presented Oprah Winfrey with the Minerva Award to honour women who make a difference.

Oprah looked stunning wearing a Victoria Beckham tromp l’oeil dress from the Fall 2010 collection. Absolutely flawless.

I’m glad she didn’t go for something safe and black.

This must have been a huge honour for Victoria, who was also in attendance, as she’s been often quoted as saying she wanted to dress the likes of Oprah and the First Lady, Michelle Obama.

As Prabal Gurung knows only too well. First come come Oprah, then comes Mrs O.

Victoria Beckham looked equally glamorous wearing a drape neck fitted dress from the same Fall 2010 collection with a clutch from her recent Spring 2011 collection.

Both look amazing.
