Jack Whitehall accidentally "ruined" Harry Styles' suit with wine after knocking back tequila.
The comedian spilled his glass of white wine over the singer's banana yellow two-piece while he interviewed him in the audience of the star-studded Brits on Tuesday.
In hilarious scenes, Jack was taken back when he realised he had spilt his booze all over the former One Direction star's lap during his grilling.
He exclaimed to his interviewee: "Oh my God, I've ruined your suit!"
The cheeky Brits host joked Harry was "going off the rails" when he knocked back some of the singer's neat tequila at the table.
He said: "That's neat tequila. He's gone off the rails. Lizzo, that's neat tequila. Oh my God."
In good humour, Jack poked fun at Simon Cowell's changing looks as he quipped Harry was on The X Factor"three Simon Cowell faces ago".
The TV star also made fun of the hitmaker's outrageous outfit choice when he said he wouldn't ask what "psychedelic drugs" his stylist had been on while picking the ensemble.
He said: "[Harry was on The X Factor] three Simon Cowell faces ago. You're not allowed to laugh about that.
"You talked about psychedelic drugs, ITV doesn't condone that so I wont ask which drugs your stylist was on."
Jack took to Instagram to share the funny clip from the show on Tuesday with his loyal admirers.
The host wrote in the caption: "New show. Me, @lizzobeeating and @harrystyles travelling around the world in a camper van. @brits #BRITs."
Elsewhere, Jack was left red-faced as singer Lizzo outrageously flirted with him and Harry.
The BRITs presenter was clearly not ready for the American singer's quick-witted quips during their chat at the awards show.
In response to his question about performing at Glastonbury, she failed to answer and said she had got "lost in his eyes".
Flustered Jack tried to change the subject by addressing her "very racy performance" with Harry.
