Kim Kardashian and her 8-months pregnant sister Kourtney celebrated the 30th birthday of fellow celebutante Courtenay Semel at Il Sole last night.

It's kind of hard to believe this generation of Filthy Rich girls are turning 30 (especially when some of them still behave like they're 12), but maybe entering a new decade will bring a new maturity to Courtenay's life!

Or at least a bunch of kickass gifts!
