Singer and E! reality star Christina Milian has joined the cast of John Stamos's Fox pilot.
The 33-year-old singer will also join Paget Brewster in Grandpa, which stars Stamos as Jimmy, who is enjoying his bachelor lifestyle until he finds out that he's not only a father but also a grandfather.
According to Deadline, Milian will take on the role of Vanessa, a "hot mess" who had a one-night stand with Gerald (Josh Peck), Jimmy's son, and they now have a 2-year-old daughter.
Meanwhile, Brewster will star as Sara, Jimmy's ex-girlfriend and Gerald's mother.
The Office's Danny Chun penned the script, while Chun and Dan Fogelman are executive producing.
