Pop star Daniel Bedingfield has undergone a study amid fears he suffers from a sleep disorder.
The Gotta Get Thru This hitmaker visited a clinic on Monday night (04Jun12) where doctors ran tests to confirm he has developed sleep apnea, which causes abnormal breathing while the sufferer dozes.
The singer posted a number of images on his Twitter.com page which showed him hooked up to equipment allowing technicians to monitor him as he snoozes.
Taking to the social networking site, the star writes, "So I guess I have sleep apnia (sic) and I'm going in to do a sleep study to find out why."
