KERRY Katona has taken a savage swipe at Fern Britton and reignited their feud over her infamous This Morning interview.

In 2008 Kerry was interviewed by Fern, 66, and Phillip Schofield on This Morning and was seen “slurring” her words as a result of her medication for bipolar disorder.

However, at the time, Fern asked the former Atomic Kitten singer if she was an alcoholic.

Last night Fern was involved in a clash with Nikita Kuzmin and fans later branded her “patronising”.

Kerry also took to Instagram to share her thoughts, saying: “Is Fern a little bit drunk?

“I think Fern has had one too many in the house and she is drunk.”

Then imitating the former This Morning presenter, Kerry added: “Fern, are you an alcoholic or is it your medication?”

There is nothing to suggest Fern was drunk during last night’s episode of Celebrity Big Brother.

Fern previously quizzed Kerry on her battle with addiction, asking: “A lot of people say when you have an addictive personality and give up one addiction it is replaced with another. Is it alcohol?”

On reflection, Fern later said: “That opened the gates of misunderstanding and upset. You don’t intend to upset anybody, but I managed to.”

However, Kerry previously insisted she had no problem with Fern, Phillip or This Morning.

She said: “I’m glad it happened now because I can talk about mental health and addiction.

“I hated Phillip, hated Fern, hated ITV, hated This Morning, but now I love you.”
