Party time!
Caitlyn Jenner celebrates her 66th birthday today, and you can bet they'll be plenty of laughter and dancing to ring in the occasion. As we've seen on her show numerous times, the reality star and fashionista loves to bust a move, whether she's kicking up her heels or raising the roof!
In celebration of Cait's big day, look back at the funniest and most endearing moments from the first season of I Am Cait, including that time she had a bit of a fumble on her roller skates! She still looked good though!
Happy birthday, Caitlyn!
Stay tuned for the return of I Am Cait in 2016, only on E!
