Ryan Seacrest will be at Children’s Hospital Orange County Monday broadcasting live, but he won’t be alone.

The Radio Lollipop project is bringing the entire KIIS on-air line-up out to raise money for C.H.O.C. and its patients. This is the fifth year the team has spearheaded the charity broadcast.

Celebrity guests also appearing are Emily Osment from Disney Channel’s Hannah Montana, Nolan Gould and Rico Rodriguez from ABC’s Modern Family, Kyle Massey from Dancing With The Stars, and cast members of MTV’s The Buried Life.

RCA recording artist, Mike Posner, will perform his hit single, Cooler Than Me, live at CHOC.

And Kai Lan from Nickelodeon’s Storytime Live show will be reading to the patients and their families.

The activities planned for patients and their families are autograph sessions, story telling, coloring contest, bake sale, carnival games and more.
