Usually, we will see celebrities celebrating their birthdays in some unique ways. Regina Hall turned 50 over the weekend and instead of a big bash or photoshoot, the actress decided to give us a celebratory song, which, will definitely get stuck in your head. Basically, Regina admits that she is an "old bitch." In her caption of her song and video, she says, "Because laughter keeps you forever young I wrote a special song for a special Birthday." And she wasn't dolled up for the song and video. Regina kept it really low key in lounge wear and undone hair. Hey, why not? Happy birthday, Regina!
