Viewers who tuned into This Morning got a little more than they bargained for yesterday as Fern Britton displayed her ample cleavage in a low cut top.

But those hoping for a repeat performance today were left disappointed as Miss Britton decided to cover up in a high necked jacket.

Perhaps Miss Britton can't be blamed for yesterday's chest-baring show. When you have to sit next to the curvaceous Kelly Brook on the sofa a lady can’t be blamed for trying to keep up.

In Miss Britton’s case, however, it was more a matter of how low she could go.

While Miss Brook, 28, went on yesterday's This Morning in a revealing red dress, Miss Britton boasted an even lower neckline that showed off a stunning cleavage.

Battle of the busts: Kelly Brook and This Morning presenter Fern Britton both boasted plunging necklines on the show yesterday

In her figure-hugging brown dress, she was in high spirits as she and co-host Phillip Schofield interviewed Miss Brook about her new show on Living TV and star role in the West End play Fat Pig.

The 51-year-old presenter has slimmed dramatically in recent months. In fact she has returned to the ITV daytime show after the summer break looking trimmer than ever.

It has been a difficult few months for Miss Britton following revelations that much of her weight loss has resulted from gastric band surgery. She lost five stone, dropping from size 22 to 16.

What a beauty: Kelly wore a stunning red dress with a plunging neckline but Fern fought back with her own revealing frock

‘It’s taken me two years and a lot of hard work,’ she said at the time.

Some viewers felt they had been misled and she missed four editions of This Morning with 'nervous exhaustion' at the height of the affair.

But after a few weeks away from the sofa, and a trip to Cornwall with chef husband Phil Vickery and their children, it appears that a refreshed Fern has put the affair behind her.
