Ashley Roberts treated by medic after rat bite

Former Pussycat Dolls star Ashley Roberts was treated by medics on Thursday amid fears she had been bitten by a rat during her stint on I'm A Celebrity... Get Me Out Of Here!.

The U.S. singer signed up for the three-week survival challenge in the Australian jungle and she is already struggling after taking part in a stomach-churning 'trial' to win meals for her campmates.

Roberts had to confront snakes, cockroaches and other critters as part of the Terror Train task but the challenge was dramatically halted when she claimed she had been "bitten by a rat".

The show's on-site medic was sent in to examine Roberts and declared her "fine", and the pop star was allowed to proceed with the trial.

She eventually won eight meals for her fellow campmates, who include heavyweight boxer David Haye and actor and former Doctor Who Colin Baker.
