The Kelly Clarkson Show has gone on without its host, and guest hosts including Wanda Sykes, Brooke Shields, and Kevin Hart, Roy Wood Jr., Simu Liu, and Willie Geist have stepped in to fill her shoes. Molly Sims returns to host the show today, March 14. The unexplained absence has caused concern among Clarkson’s fans.

Since Feb. 28, Kelly Clarkson has missed several episodes of the show. She didn’t appear in the March 3 taping of the show and was replaced by guest host Simu Liu who revealed that he learned about the gig “five minutes” before stepping out on stage, where he was supposed to attend as a guest.
