Wendy Williams is allegedly “super scared” that she is going to lose her show since taking time away in December to deal with health issues. “Watching [fill-in host] Nick Cannon being a huge hit with her audience is tough for her,” an insider tells Page Six. “They’re already starting to mess with the format. It’s like watching them screw around with her baby.” Cannon filled in for Williams Monday through Wednesday this week, while American Pie actor Jason Biggs hosted Thursday’s edition of the show. Other guests hosts are booked through February 15. While details about Williams’ absence are scarce, her family said in January that she had been hospitalized because of complications related to her Graves’ disease; she also fractured her shoulder in December.
