Alex Jones gave the Norovirus to Lionel Richie after he planted a kiss on her lips.
The One Show host joked the singer, who had to cancel two of his gigs after contracting the infection by pecking her at Glastonbury, should have just gone for her cheek to avoid having to cancel two of his gigs as a result.
She told The Sun: “After Lionel and I had just finished our chat on the show, I went to give him a kiss on the cheek and he went in for the lips.
“He caught the Norovirus off me and had to cancel two of his tour dates.”
