Olivia Wilde struck a pose this afternoon at the Power of Women luncheon in LA, while elsewhere the news broke that her costar Jennifer Morrison will be leaving their series House. Olivia was joined by a fresh-off-the-Emmys-red-carpet January Jones, along with Anne Hathaway and AnnaLynne McCord. Christina Aguilera was also in attendance, as her husband Jordan Bratman dared to be one of the few guys in the room. The event was designed to honor eight ladies — Christina Aguilera, Christina Applegate, Maria Bello, Anne Hathaway, January Jones, Sigourney Weaver, film executive Sherry Lansing, and producer Laura Ziskin — who all maintain their commitment to charitable causes despite their hectic Hollywood careers.

Lots more photos of the Variety, including Christina Applegate, Maria Bello, and Cheryl Hines, so read more.
