Collabro return to Britain's Got Talent 2019 this weekend for The Champions spin-off.
Britain's Got Talent: The Champions is currently airing Saturday nights on ITV, hosted by Ant and Dec just like the main show.
It will see acts from the past 13 years of BGT as well as other Got Talent series from across the world compete to be named the ultimate champion.
Collabro are one of the confirmed acts to be taking part, appearing in this weekend's fifth heat.
The musical theatre boyband won the show in 2014 and have since enjoyed a string of successful albums and tours.
They recently revealed a brand new album and tour as they prepare for a comeback on Britain's Got Talent.
They said on social media: "We can’t wait for you guys to tune in! We had such a great time seeing our BGT family again and meeting our fellow Champions. - The boys x"
Collabro perform a cover of Queen's Who Wants To Live Forever for their Champions performance.
