Watch as the youngster makes another appearance on the Ellen Show this week.
5 Year-old Kai Langer, who you might remember from his Bruno Mars cover on the Ellen DeGeneres show last year, has returned to provide another heart-warming cover to the audience.
The youngster decided to wow with a version of Katy Perry's 'Roar' this time and also had a little chat about what he's been up to since his last appearance.
Meanwhile, Katy has been busy this past weekend after being spotted partying in New York with Rihanna as well as visiting Neil Patrick Harris on Broadway.
She's also been spotted getting close with producer Diplo as rumours of a romance between the pair hot up.
