Will.i.am got a rude awakening at his #Willpower album listening party at The Avalon in Hollywood last night - his custom-made coupe was stolen!

The Black Eyed Peas singer had driven pal Nicole Scherzinger to the bash in his pricey ride, only to discover it was nowhere to be found when he left the party at 2am, causing him to unleash a firestorm of angry tweets. "My car was stolen... what the f**k..?" he wrote on the microblogging site, adding, "I'm going to be optimistic and pray that my car is returned and safe..."

Earlier in the night, the pair had posed by the rapper's fancy wheels, which was a prototype made by West Coast Customs using pieces borrowed from a donor Delorean and a Dodge Challenger. This isn't the first time the car has gone missing, either! It was impounded in June by police for being unregistered, only to be returned once Will.i.am provided the necessary paperwork.

Back in 2010, the Grammy winner's Bentley was broken into, whereby $10,000 worth of various items were stolen.

Let's hope he has theft insurance!
