Nick Cannon is strutting his stuff all over the Peacock: The America’s Got Talent host has now signed on as a recurring cast member of the new NBC comedy Up All Night, the network confirmed today. (TV Guide first reported the news.) Cannon will play Calvin, a spirited talk show emcee whose popularity irks co-host Ava (Maya Rudolph). In addition, Jennifer Hall (Nip/Tuck, CSI: Miami) will recur as Missy, Ava’s unconfident assistant. Up All Night, which debuts Sept. 14, also stars Christina Applegate and Will Arnett as new parents, with Applegate’s character, Reagan, serving as Ava’s producer.
