Matt Lucas took to the Britain's Got Talent stage as part of the incredible cast of Les Miserables in a special musical performance.
A medley of songs from Cameron Mackintosh's Mary Poppins, Phantom of the Opera, Les Miserables wowed the judges, who gave the show at standing ovation.
This included David Walliams, who was Matt's comedy partner when they starred in shows including Little Britain.
Matt played villainous landlord Thénardier, a role played by fellow comic Sacha Baron Cohen in the 2012 film.
One viewer gushed: " #BGT Matt Lucus .. by far the best landlord.. can't wait to see live".
Another penned: "Matt Lucas and David Walliams back on TV together (albeit distanced)".
A third pointed out: "First time matt lucas and david walliams have been on bgt together #BGT ".
A fourth tweeted: "Les Mis my absolute favourite west end show. Missing theatre so much. #BritainsGotTalent @RealMattLucas brilliant".
Another called the moment a "little Britain reunion ,David and matt Lucas".
Cameron Mackintosh made a plea to the chancellor Rishi Sunak to get theatres reopened as he said it was a travesty the performers had not done a show in seven months.
The theatre industry has been one of the hardest hit by the pandemic, and Cameron begged Rishi to reopen them by spring next year.
Meanwhile, singer Jon Courtenay won the show, beating nine other acts and winning £250,000 and spot in the Royal Variety Show.
"This morning for the first time, this sounds really dramatic, but I woke up with an idea for a song for the Royal Variety performance.
"I wrote it down and I tried not to think of it as a sign, because that would be too much pressure, but... Just amazing, I can't actually believe it," he gushed.
