Holly Willoughby is off from presenting ITV's This Morning for a "few days" due to having shingles.
The ITV talk show host has been away during the Easter holidays along with Phillip Schofield. He returned to the programme on Monday.
In an Instagram post, Willoughby: "Hi... Just to let you know I may be away for the rest of the week as I have shingles... I'll be back as soon as I'm better. Huge love, Holly."
The infection, which causes a painful rash, is caused by the same virus as chickenpox.
According to Mayo Clinic, the varicella-zoster virus stays in your body and when it is re-activated, blotches appear on the skin. Patients report feeling generally unwell and like they have a headache.
When Willoughby and Schofield, who also present ITV's Dancing on Ice together, are not hosting their ITV talk show, TV personality Alison Hammond and former The X Factor presenter Dermot O'Leary step in as hosts.
On Monday, The Hit List presenter and former The Saturdays singer Rochelle Humes was in the studio alongside Schofield to host.
