Donnie Wahlberg from Blue Bloods
Before he became Detective Danny Reagan, Donnie Wahlberg was a singing sensation.
Made famous as one of the members of the boy band New Kids On The Block, Wahlberg's song and dance skills started way back in the '80s when he performed hits like "You Got It (The Right Stuff)" and "Step By Step."
These days, Wahlberg manages to find the time to remove his shield on occasion and continues to tour with his bandmates in NKOTB.
