Rick Astley surprised fans after he performed his own acoustic rendition of Biffy Clyro's hit Many of Horror.
And fans demanded an instant collaboration with the Scots rockers after he wowed them with his performance.
Never Gonna Give You Up singer Rick who is also known for his now viral Rickrolling videos when someone trolls another person by linking out to Rick Astley's classic 1987 earworm, "Never Gonna Give You Up" while claiming the link is something else.
Rick who comfortably sang the big rock song even said 'Mon The Biffy' at the end of his rendition.
He congratulated the lads on their recent Brit Award nomination saying: "Congrats Biffy Clyro on your Brit Awards nomination! Here’s a little cover of ‘Many of Horror’ - Rick x #BRITsCovers #RickTok @biffyclyro "
Rick has been a big fan of Biffy Clyro for a while and told The Quietus in 2018 just how he got into them through a neighbour's kid.
He explained: "...They used to play me records and I used to ask 'what is that?' - one of these bands were Biffy Clyro.
They didn't really register with me because they were a bit too intricate but I was driving home one night, coming up Kingston Hill and this record came on and I had to pull over to the side of the road as I was shedding tears.
"And the song was 'Many Of Horror'. And I thought 'this is the best thing I've heard in quite a while' but I didn't know it was Biffy Clyro! I just went 'ooh!'.
"I went home, bought it on iTunes and played the song about 25 to 30 times, crying my eyes out. Something in that song flipped me out completely. It's quite an anthemic, emotional song.
Rick said he emailed the producer of the record and told him the song had 'completely and utterly blown me away'.
He added "He mailed back and said 'thanks very much for that, really appreciate it'. I've never done that before or since!"
Following his Biffy Clyro song cover, fans asked for him to collaborate with the Scots.
Dapper Laughs also said he wanted to hear a 'Rick Astley Rock album now' and Nati Dredd also said 'Absolutely beautiful. Mon the biff, Mon the Rick."
