Gavin James is getting real big, real fast; and tonight, the Bitter Pill singer will be performing on hit U.S show Jimmy Kimmel Live.

This year Gavin was signed Capitol Records – home to Katy Perry, Troye Sivan, and Mary J. Blige – and supported Ed Sheeran in Croke Park. Not a bad year so far!

We’re betting he’s going to get as big as fellow Irish star Hozier!
