After about a minute and a half of solo lip-syncing “Down On Me", #50Cent himself pops out of Cahill’s bedroom closet. They turn up the swagger and finish the song, with 50 letting Keenan borrow his bling. A Moment #Cahill Will Never Forget With 50 Cent.❤ #KeenanCahill | The Real G Music | Facebook
