'This Is Love' superstar Will.i.Am still appears to be missing his car after it disappeared from outside of his album launch party in the early hours of Tuesday (August 14).

The limited edition sports vanished from the parking lot of The Avalon yesterday and he expressed his shock at finding that the vehicle had been stolen by posting a series of incredulous messages on his official Twitter page: "My car was stolen...what the f*ck... Where is my f*cking car...??? This isn't funny anymore."

Although it was reported late on Tuesday night that the car had been returned, he continued posting about the loss and even questioned if teen sensation Justin Bieber had something to do with it for his practical joke show, 'Punk'd': "@justinbieber are you punking me???"

A fellow Twitter user then directed Will.i.Am's attention to a video uploaded to YouTube in which a masked individual recites a riddle about the situation, prompting him to write: "What the hell is this??? This is getting old...#wheresmycar."
