GOOD Morning Britain's Dr Hilary Jones performed a self-penned rap on the show today - but admitted it could be viewed as "cultural misappropriation".
The 67-year-old revealed his secret music career as Kate encouraged him to tell viewers about his one-time hit.
She said: "You and I have known each other a long time.
"I remember Hilary indulging in the world of rap. Do you remember that years ago?"
Hilary said: "I do. I wrote a rap song about the dangers and misuse of anabolic steroids."
Alex said "We've got to hear it, I wasn't born [when it was out]."
Hilary admitted: "This would be cultural misappropriation these days.
"The first word went something like this...
"I'm a body builder, I've got legs of iron.

"I've got the broadest shoulders that the broads just love to cry on. Antibolics, antibolics..."
Kate laughed: "It didn't make it to the top of the charts, but it sent an important message which is why I love you, Hilary."
Alex barely reacted to the rap.. instead reading his notes for the rest of the show.
