Smokin' hot sisters Joanna and Marta Krupa celebrated Joanna's 31st birthday at Trousdale last night, along with celeb friends like Ryan Seacrest and Stacy Keibler!
Course we know Lindsay Lohan and Samantha Ronson were also at the club last night, maybe one of them wished the model hottie a happy birthday... hopefully not by throwing a glass at her head!
So many people at Trousdale!
