REALITY TV star Kerry Katona has shocked viewers with an erratic appearance on ITV's This Morning.

She slurred her words and frequently looked around the studio calling for her husband Mark Croft as she was interviewed by presenters Philip Schofield and Fern Britton.

Warrington-born Katona, 28, who lives in Wilmslow, was discussing her recent cosmetic surgery.

Schofield asked her: "You don't seem right to me, you've got the body sorted but your speech is a bit slurred, how are you feeling?"

Katona glanced off camera and seemed shocked as she asked: "Is it?"

She then admitted her speech may be slurred but said it was because she was taking prescription drugs.

She said: "That's because I'm on medication at night-time. I had some last night, didn't I Mark?" before trying to see her husband amongst the crew behind the camera.

Schofield said he was only asking her "what people watching at home would be thinking" and that producers were telling him via his earpiece that they were already receiving calls about her behaviour.

Britton also asked the star about recent claims in a magazine that she had been drinking while on holiday.

A smiling but obviously rattled Katona answered: "No, not at all. I'm on holiday in Spain and I'm allowed to have a drink, aren't I?"
