Happy 38th birthday to the one and only Kat Dennings! Today, you officially entered the late 30s club and we have a feeling you'll make it look as fabulous as ever. From your iconic roles in "2 Broke Girls" and "Thor," to your witty sense of humor and killer fashion sense, you continue to inspire and entertain us. Cheers to another year of making us laugh and being an incredible human being. Keep slaying and never stop being you!
