Michael Peter Balzary (born October 16, 1962), better known by his stage name Flea, is an Australian-born, American musician and actor, known as the bassist and co-founding member of the rock band Red Hot Chili Peppers.

Flea provides his own voice in "Peter's Def Jam" when Stewie tries to drive Brian out when they are forced to share a room when Lois starts suffering from allergies. After Brian's slovenly ways get on Stewie's nerves, he points out that he is the cause of their recurring flea problem, and is forced to drive out the bassist. As he shoves him out the door, he orders him to put on a shirt, reminding him that he is fifty. Flea corrects him by noting that he is fifty four.
