Today Thalia turns 42, but her birthday festivities started this past weekend. The singer partied with her music producer husband Tommy Mottola and close friends. Posting a set of pictures and messages on Instagram reading, Happy Birthday to me, and let the party begin! With a birthday cake message reading both in English and Spanish, Thalia also shared a pic of how she ended up with cake all over her face. She followed with a post saying, wait until I get you back and we’ll see how it goes. Pay back!
