Studdard Has Cameo in ‘Scooby-Doo’ Sequel
LOS ANGELES – The Velvet Teddy Bear has teamed up with a digital dog.
“American Idol” star Ruben Studdard said Monday he’s shot a cameo role as himself for next year’s mystery-comedy “Scooby-Doo 2: Monsters Unleashed.”
The bulky crooner, who defeated his skinny rival, Clay Aiken, last month on the Fox talent contest, said he doesn’t help Scooby and his gang solve the mystery. “I’m just in at the end of the movie. I’m having a party and singing in the end. It’s cool,” he said.
In the movie, Freddie Prinze Jr., Sarah Michelle Gellar, Matthew Lillard and Linda Cardellini confront an anonymous masked villain menacing the city of Coolsville with a machine that creates ghosts and monsters.
