The Mean Girls star celebrated her 27th birthday at  Tabu Ultra Lounge at The MGM Grand Resort in Las Vegas, Nevada on Friday (Sept 18).

Actress Lacey Chabert donned a sparkly emerald and gold strapless dress, and partied the night away with her mom (aww cute!) and a group of close friends.

At one point in the night, our spy said the entire club wished Lacy a happy birthday!

Ring it in, girl!
