Strictly Come Dancing fans were treated to an adorable throwback clip of AJ Pritchard and his little brother Curtis tonight.
AJ, 24, was on tonight's The Professionals spin-off when he was shown a clip of him and the Love Island star, 23, from when they were kids.
The brothers were dressed up in 70s style catsuits as they performed Night Fever in a school play.
They performed a hilariously cheesy routine that involved a lot of finger pointing and hands being run through hair.
AJ was both embarrassed and tickled by the video, saying: "Oh my god! That's me in white and Curtis in black."
He was watching alongside fellow professional Neil Jones, who poked fun at the boys' youthful looks.
Neil said: "Is this last year?"
The clip then changed to a shot from the same play in which AJ is given his own line to say.
"I am the trendiest dude in the joint," he declares.
Curtis and his girlfriend Maura Higgins attended the Strictly launch party last month in support of his big brother.
Both are professional dancers, with Curtis appearing on the Irish version of Dancing with the Stars before entering Love Island.
He and Maura were a late couple in the villa after Curtis cooled things off with air hostess Amy Hart following the dramatic Casa Amor segment.
Curtis had his head turned by the stunning Jordan Raine while Amy was ready to declare she was madly in love with the dancer.
Maura didn't waste any time in flirting up a storm with Curtis when his relationship with Amy broke down.
The couple made it to the Love Island final and came in fourth place.
