Kerry Katona's husband Mark Croft has rubbished claims his wife was drunk during a day time TV interview.

Mark told reporters that Kerry's slurred speech was the result of taking her prescription medication too late the previous night.

The former Atomic Kitten's early rise to appear on This Morning with Fern Britton and Phillip Schofield is also said to have contributed to her erratic behaviour.

Mark tells mtv.co.uk, “Due to the TV commitments Kerry had last night, Kerry was four hours late in taking her medication for an ongoing bi polar condition.

“One of the side effects of her drugs is slurred speech and as Kerry took the drugs late and was up early it was particularly bad today.

“Kerry would like to categorically state for the record that that the only thing she drank before the show was cups of tea.

He added, “Kerry was upset at the insinuation that she was on anything other than the prescription drugs which she has always been honest about taking.”
