Good Morning Britain star Susanna Reid broke out in a bizarre rash while she was presenting the show – and jokingly said co-host Piers Morgan could be to blame.

Susanna, who was sporting a blue M&Co floral dress, appeared to be suffering from bizarre blotches on her right arm.

After Piers said to Susanna: “You’ve come out in some weird rash,” his co-star replied: “It’s because I stroked your arm earlier, and now my skin has come out in a rash.”

This prompted Piers to suggest that Susanna might even be allergic to him, to which Susanna remarked: “It’s what I suspected all along.”

Ever the gentleman, Piers said he would steer the GMB ship without his co-star, telling viewers: “Well if we lose Susanna, relax I will still be here and Ranvir will still be here. That’s showbiz.”

Luckily Susanna managed to remain on the sofa for the rest of the show.
