"I would always champion the artist."
But Sheeran, 26, didn't have an easy time of it as Foxx decided to test his skills in front of a live audience.
He said: "I took him down to this show I was doing every Monday ... and there was like 800 black people. Just the best musicians...
"And he pops out with his little red hair and a ukulele ... and he went out there on that ukulele and got a standing ovation for 12 minutes. The rest is history."
Foxx, 49, is not the only Hollywood star to give Sheeran a place to stay; back in 2014, Sheeran revealed he had been living rent-free at Courteney Cox's Malibu beach house.
He said: "There was no rent but I made the bed and cups of tea and things like that. If you're staying at your friend's house, you should treat it like your own.
"Well, actually, that's a lie - because I don't make my own bed at home."
