Nick Jonas has assured fans he is recovering well after a mystery illness forced him to cancel a weekend gig with his new band.
The 17 year old has been touring the U.S. with his new group, Nick Jonas and The Administration, but they axed a gig in Denver, Colorado on Sunday (24Jan10) because the star was feeling unwell.
But the teenager has taken to his Facebook page to tell fans he is on the road to recovery.
He says, "I am feeling much better! To everyone in Denver, thanks so much for all the well wishes and I apologise again that this has happened."
The band performed in Los Angeles as scheduled on Tuesday (26Jan10) night.
