After Jay James’ performance of New York, New York Louis, 62, claimed the sexy dancer in a martini glass was too distracting.
CHERYL FERNANDEZ-VERSINI SLAMS NADINE COYLE: "SHE'S FULL OF SH*T!"
But cheeky Simon, 55, was quick to retort: “We know YOU weren’t distracted!”
Louis attempted to defend himself, but Simon shot him a seemingly knowing look.
Watch the moment for yourself below:
Immediately viewers picked up on Si’s ‘dig’. One user tweeted: “Love how every week Simon Cowell insinuates Louis Walsh is gay.”
Another wrote: “Did Simon Cowell just call Louis Walsh gay???”
Louis has never publicly spoken about his love life, and last year refused to open up about his sexuality during an interview.
He said: “Don’t go there. I can’t. I think your private life is your own private life.”
Simon appeared to be in a particularly catty mood during Saturday night’s episode of the singing competition.
Commenting on Jay’s performance, Mel B said: “I think Simon did you a disservice, if it wasn’t for Brian’s theatricals that would just be a bad vocal.”
Cheryl Fernandez-Versini also commented negatively, but Simon hit back: “We have three Debbie Downers on the show tonight. This was the best performance of the night.”
