Despite being mates with Jack Johnson, James Morrison and James Blunt, it's taken Jason Mraz a few years to get in to the UK charts.
'I'm Yours' is taken from Jason Mraz's third studio album 'We Sing. We Dance. We Steal Things', which is currently sat in the top 10 album chart.
The song was originally released in June last year but failed to make an impact, this lead to the song being re-released before Christmas.
Take a look at the video for 'I'm Yours' which was shot on the Kauai and Oahu islands of Hawaii...
