It was a chance to look pretty in pink and Anne Hathaway certainly jumped at that opportunity when she pitched up at The Pink Party in Santa Monica, California.
The One Day star was looking fab in an adorable pink J Mendel shift dress, which matched the theme of the event perfectly.
She combined the pink with a black clutch and a pair of black heels. For the beauty, Hathaway kept it simple (of course).
But not everyone dressed to match the name of the party, instead of a cute pink frock, Poppy Delevingne opted for something a little more dramatic.
The duo were joined by the likes of Kate Beckinsale who wore a Donna Karan dress and was carrying a cute Jimmy Choo bag. Have a look at all the looks below...
