THE SOPRANOS star Robert Iler celebrated his 21st birthday in Las Vegas, Nevada, by partying like a rock star and gambling away all his money at the roulette table. The troubled star, who plays son AJ SOPRANO on the show, has previously been arrested in two robbery incidents and also for marijuana possession. Iler rang in his 21st birthday, which means he can legally drink alcohol in the US, at Tao at the Venetian Hotel/Casino on 3 March (06). Newly-single Sopranos co-star Jamie-Lynn Sigler joined him and hundreds of partygoers watched as the actor dirty-danced and screamed along to rap songs. The actor, clad in a white suit, later turned his attention to the roulette table, where he reportedly lost all of his money betting on the number 21.
