There are concerns that some stars, including Sharon, have become too thin after using Ozempic after the Osbourne star admitted she was struggling to put on weight despite having quit the medication.
However, when Hollywood A-lister, Brian, 78, was told how well he was looking on the Jonathan Ross Show, which airs on the weekend, he admitted he was taking Ozempic - but made it clear he was using it for the purpose for which it it's intended.
A whole host of celebrities, such as Sharon Osbourne, have taken the drug - which is used to treat diabetes - for weight loss.
She lost 42lbs but has since admitted she is desperate to put some weight on but can't - despite having quit the medication.
Ozempic is a brand name for semaglutide, a medication used to treat type 2 diabetes.
