Wendy Williams has canceled all public appearances amid "ongoing health issues".

The television host was due to take part in a number of promotional activities for The Wendy Williams Show this week, but has canceled her plans after being struck by unspecified "health issues".

A post on Wendy's Instagram account reads: "Wendy is dealing with some ongoing health issues and is undergoing further evaluations.

"She will not be able to complete her promotional activities next week, but can't wait to be back in her purple chair Monday, September 20th for the 13th season premiere."

Although her health issues were not specified, Wendy previously took a break from her daytime talk show in Spring last year after her battle with Graves' disease left her too "fatigued" to film.
