Famed singer and actor Donnie Wahlberg was born Donald Edmond Wahlberg Jr. on August 17, 1969, in Boston, Massachusetts, a predominantly Irish-American suburb of Boston. He was the eighth of nine children; his younger sibling, Mark Wahlberg, is also a famous entertainer.
After a 45-day jail term at 16, Wahlberg turned his life around via the music world with the help of his brother Donnie, a member of New Kids on the Block. Wahlberg transformed from rapper to Hollywood actor and never looked back, starring in films such as Boogie Nights and Three Kings.
