Robin Thicke teams up with dad and young son for new song

Robin Thicke has turned his new song Ain't No Hat 4 That into a family affair by co-writing the tune with his actor dad Alan Thicke and inviting his young son to perform over the intro.

The upbeat track from his forthcoming album Blurred Lines features Julian, his three year old with wife Paula Patton, repeating the song's title, as well as lyrics from former Growing Pains star Alan, who previously worked as a TV theme song composer, penning themes for TV sitcoms The Facts of Life and Diff'rent Strokes.

The collaboration debuted on music website Rap-Up.com on Wednesday (17Jul13).
