Today is Sterling Knight's 26th birthday! Even though we love watching him on Baby Daddy, we still get super-nostalgic about his Sonny With a Chance days. The actor played Chad Dylan Cooper on the show, and we miss his insane chemistry with Demi Lovato (when their characters were flirting and fighting in equal measure) as well as the antics they got into in the series.
