Laughing loudly at a joke, Katy – who was sat between judges Lionel Richie and Luke Bryan  – suddenly looked horrified and called out: “I just split my pants!”

As the audience roared with laughter the blonde singer stood up to reveal the unfortunate split to the crowd.

Lionel can be seen trying to help his red-faced fellow judge as she wanders helplessly around on stage.

Before long, an assistant rushes up to her to tape the oufit back together.

It comes just weeks after the American pop star drooled all over her boyfriend Orlando’s “washboard” abs on Instagram.

In February The Sun Online exclusively revealed the couple had reunited almost a year on from their split.

They have been pictured together on a number of occasions since and on Friday Katy couldn’t help but admire her boyfriend’s bod after he posted a shirtless snap on his Instagram page.

Orlando, 41, wrote alongside the picture of him standing topless in a bathroom while looking in a mirror: “#tbt capetown ‘Brian fit’ for #zulumovie this photo saved not JUST for vanity but as a lil reminder that I got to that place and I know how to get to that place when I need to go to that place.

“Diet-lifting-hours of #nopainnogain and a #mindfulness presence and #focus that just won’t settle.

“Nothing but respect for those who can maintain it I try to stay close which is good because im heading back in that direction for Killer Joe soon to be at the @trafalgarstudios 18th may.”

His cheeky girlfriend then wrote in the comments section: “Oh hey! I was actually looking for a washboard to do me laundry on.”

Their romance is clearly back on track, eleven months after they split.

Last month, an insider close to the pair told The Sun Online: “They’re back on. Katy wants to make things work this time around.

“She tried, but she couldn’t cut him off. She cares too much about him. This time, they’re keeping things low key – but they’re back together.”

Rumours that the pair had reunited started in January when both Orlando and Katy were spotted on holiday in the Maldives.
