If the caption ("Best birthday cake ever. Thank you mama ..." ) is to be believed, Willis received the cake from mom Demi Moore.
Willis also posted a cute selfie with a heartfelt birthday message: "I want to say thank you to everyone who helped me get here … I thank you all because I would not be the woman I am today without all of you. I can't wait to see what adventures await me."
The Willis/Moore family is currently dealing with daughter Tallulah's decision to enter rehab.
