Celebs were out in force in Hollywood Saturday night, and they didn't fool us.
Abigail Ratchford certainly was hiding in plain sight. Kylie Jenner was true to form, dressing as Christina Aguilera in the "Dirrty" vid, which is hot.
As for Tyga ... well, he dressed as a successful rapper, Juelz Santana.
Check out Matt Bellamy, Elle Evans, Tera Reid, Kate Hudson, Taylor Lautner, Kourtney Kardashian, Paris Hilton, Joanna Krupa, Nick Jonas, Sofia Richie and more.
