Christina Milian is set to star in Fox's single-camera comedy pilot "Grandpa."

The show, which will also feature John Stamos and "Red Dawn" actor Josh Peck, will reportedly revolve around the character of longtime bachelor Jimmy (Stamos) who suddenly discovers that he has a son named Gerald (Peck). Gerald is a father of a two-year old girl, a result of "a one-night stand with the sexy Vanessa (Milian)." He longs for a strong father figure who will guide him through fatherhood, Deadline explained. Things started to get more complicated when Vanessa meets Jimmy and falls for him. 

The project helmed by ABC Studios and 20^th TV is written by Danny Chun and produced by Dan Fogelman, Indie Wire reported.

Aside from Milian, Stamos, and Peck, former "Criminal Minds" star Paget Brewster is also included in the cast as Sara, Jimmy's old girlfriend who is "a former rocker chick who became pregnant with his child 26 years ago, but has raised their child, Gerald, single-handedly," according to a separate report from Deadline. Sara didn't tell Jimmy about their son, but now Gerald needs a reliable father figure to teach him about romance, and this will prompt his mother to "disrupt Jimmy's long bachelorhood at long last," Deadline added.
