Kate Garraway is set to show off her acting chops in a cameo in Hollyoaks.

The Good Morning Britain presenter, 50, said on Twitter that she has been filming a role in a “big plot” in the Channel 4 soap.

Her scenes are due to air in September.

Garraway told her 236,000 followers on the site: “Big tks to the @Hollyoaks gang 4 making filming my small part in a big plot for sept- so much fun!!!
