Gavin James was coolness personified last night as he appeared on CBS' new(ish) Late Late Show with James Corden.
Equipped with nothing more than his trusty acoustic, he performed 'The Book Of Love' with no visible signs of being concerned about the 20 million folks watching at home.
The show's other guests were Arnold Schwarzenegger and comedienne Whitney Cummings.
Having been championed by the likes of Ed Sheeran, James bagged a Stateside deal recently with Capitol Records and is currently running around North America with Kodaline.
