Rangers fan Grado has shown his true Blue colours - by serenading boy band star Duncan James.
The wrestling ace today posted a hilarious online clip of himself crooning Blue's hit song "All Rise" as bemused former frontman James looked on.
Grado got the lyrics to the 2002 number three hit horribly wrong, singing "One for the money and the re-rise, three for the thighs that you denied, all rise."
A finger-wagging James is seen chastising the Scots Squad star, telling him: "You need to learn the words mate"
But that didn't stop Grado boasting about his performance on Twitter as he bragged: "ya dancer just attempted a duet wae duncan fae blue."
Watch the clip for yourself below.
