Ben released his rendition of 'Something I Need' on Sunday night, shortly after winning the eleventh series of X Factor over bookies' favourite Fleur East.
And One Republic approve!
A tweet posted from their official Twitter account reads: "Congrats to Ben Haenow for taking his version of our tune 'Something I Need' to #1 in the UK today!! We're honoured!"
Another tweet directly to Ben said: "You made it your own, man!!! Congrats on everything and thanks for picking our tune & sending it to #1! Ur killin!! Happy holidays."
Ben, meanwhile, tweeted his own thanks to One Republic for letting him use their track, saying: "Thank you for the honour of letting me release their song 'Something I Need' as my first single!'
Both Ben and runner-up Fleur had chosen the track as their winner's song.
'Something I Need' was written by One Republic's Ryan Tedder and appears on the band's top ten album Native.
One Republic performed on X Factor back in October.
