MTV has a string of projects underway for the summer and fall seasons, including a half-hour scripted comedy series from Wilmer Valderrama. Best known for his exchange student role as Fez on That '70s Show, the 28-year-old actor has had a long-standing relationship with MTV as he created, executive produced and hosted the network's trash-talking competition program, Yo Momma. Now, he will once again attempt to turn a pilot into a hit series with his new project called Baby Dolls.
