UK superstar Ed Sheeran came by the KIIS-FM studios and showed JoJo Wright how he can make a whole song with only his guitar and loop machine...

JoJo loved this so much that he put on a gold chain and two watches to get in character...for a freestyle rap with Ed Sheeran!

Of course, we couldn't let Ed Sheeran go away without playing his hit song "A-Team" for everyone at KIIS-FM...
