Brooke Mueller didn't let her troubles with soon-to-be ex husband Charlie Sheen get in the way of celebrating their twin sons' birthday, and RadarOnline.com has the pictures.
Brooke's good friend, Paris' mom Kathy Hilton, opened up her estate for the party Sunday. Nicky Hilton and her boyfriend David Katzenberg were among the guests.
Dozens of giant balloons and colorfully wrapped presents were spotted.
Charlie's youngest kids turn two on Monday.
