Kelly Clarkson is back on the air. The "Since U Been Gone" singer, 42, returned to her daytime talk show on Tuesday after being out for almost two weeks. Guest hosts had stepped in for Clarkson during her unexplained absence.

The unnamed insider added that the "Because of You" singer is "completely fine," and noted that it is "not a cause for alarm," claiming that Clarkson would be back on air on March 13—however, that was not the case. Instead, Molly Sims appeared as a guest host, telling viewers that she would also be hosting the show on March 14.
