As if the highly anticipated TV show "Scream Queens" didn't already have enough of a star-studded cast, Chad Michael Murray has now been added to that list.

The former "One Tree Hill" and current "Agent Carter" star will be appearing on the Fox series as Brad Radwell, according to Entertainment Weekly. Brad is an agent at Endeavor and the older brother to the "fratty d-bag" and president of the golf fraternity, Chad Thadwell, played by Glen Powell. Thadwell also occasionally dates Chanel No. 1, played by Emma Roberts, and is best friends with Boone, played by Nick Jonas.

Series creator Ryan Murphy announced just last week that Patrick Schwarzenegger would be coming on as Thad, the youngest Radwell. His first appearance on the show, which is also his television debut, will be at some point during an episode in November, TV Line reported. It is unclear when Murray's character will first be seen.

As if these two celeb additions weren't enough, the Fox series also brought on sitcom legends Alan Thicke and Julia Duffy to play the Radwell brother's parents, according to E! News. Thicke is best known for his starring role in "Growing Pains" while Duffy is best known for starring in "Newhart."

"Scream Queens" premieres Sept. 22 at 8 p.m. on Fox.
