The “Kelly Clarkson Show” host was reportedly off the air due to a “personal matter,” with Simu Liu, Molly Sims and more guests stepping in.

Kelly Clarkson returned to her eponymous daytime talk show on Tuesday following a sudden and unexplained absence for a little over a week. However, the singer-turned-TV personality failed to address what caused her to mysteriously disappear from her hosting duties this month.

Clarkson missed the March 3 taping of The Kelly Clarkson Show and was replaced by guest host Simu Liu at the last minute. She returned two days later but ducked out yet again, with several celebrities stepping in to take her place. Among those who have temporarily assumed the gig include Roy Wood Jr, Wanda Sykes and Brooke Shields.
