She was warned not to embarrass herself at Elton John’s posh annual charity event

After dumping husband Mark Croft, Kerry Katona is determined to adopt a glam new image.

However, it seems the fragile star, 29, still has a way to go before becoming the well-polished lady that she aims to be.

Her own management last week issued her with a list of rules to follow in a bid to avoid coming across as ‘uncouth’ at Elton John’s swanky annual White Tie And Tiara Ball.

‘Kerry’s doing really well at the moment, so the last thing her people want is for her to ruin the new image,’ a pal tells Now.

‘She was warned to steer clear of booze and smoke less. She was also told that she had to make sure that she doesn’t do anything inappropriate, like sticking her tongue out.’

Rubbing shoulders with guests including Liz Hurley, Lulu and David Walliams, Kerry donned a white designer gown to attend the ball with publicist Claire Powell and Peter Andre.

Her life now couldn’t be further from her drug-fuelled past with ex-cabbie Mark.

But her attempt at achieving a new image suffered a huge blow last week as unflattering footage of the mum of four was aired in a Channel 4 TV documentary.

The programme Kerry And Me was filmed in February and shows the star at her very worst, leaving her scared that viewers will be reminded of the ‘old Kerry’.
