The Talk co-host Sharon Osbourne will guest-star on an upcoming episode of NBC's sitcom Up All Night.
According to The Hollywood Reporter, Osbourne -- also a judge on America's Got Talent, which, lest we forget, will feature Howard Stern next season -- will play fellow talk-show diva Ava's (Maya Rudolph) archenemy on a yet-to-be-scheduled episode.
Up All Night, which airs Thursdays at 9:30 p.m. on NBC, stars Will Arnett and Christina Applegate as a married couple trying to navigate the tough terrain that is new parenthood.
