The star gave viewers a treat when he pulled down his trousers LIVE on the early-morning chat show.

Olly was appearing on This Morning with The X Factor star Louisa Johnson to speak about their recent collaboration.

During the interview with Holly and Phil, Olly opened up about his infamous ‘bulge.’

The star is known for wearing very tight trousers and the hosts used the chat as an opportunity to point out one specific picture from a recent video shoot.

The shot showed Olly in an extremely tight white tennis outfit – with a banana stuffed down his shorts.

Olly admitted that he’s often caught out wearing trousers that are too tight, and confessed that he has been forced to start donning baggier bottoms.

Towards the end of the interview, Olly was seen fiddling with his belt as he sat on the sofa.

The camera then panned to Holly who turned to the singer and asked: “What are you doing.”

Olly then stood up, dropped his trousers and squatted down on the floor.

The hilarious moment was in reference to the guide pony who was seen POOING on the set of This Morning earlier in the show.

“I thought that’s what you do on here,” said Olly as Holly and Phil burst out laughing.

The camera then zoomed in on Louisa who was seen with her mouth hanging open in surprise.

Olly then walked off set to do back up his trousers as Holly and Phil continued their hysterics.

This Morning continues weekdays at 10.30am on ITV.
