It was alleged earlier this week that businesswoman Katie, 36, threw a tantrum at 34-year-old Kerry's wedding to George Kay, because her dress didn't fit.

The reports suggested that Katie then refused to be in Kerry's bridal party, showed up in a plain jumpsuit and left as soon as the meal was over.
The Sun claimed: "[Katie] had a face on her like a bulldog chewing a wasp. She sat through the ceremony in silence and left straight after the meal."

But mum-of-five Kerry has blasted the claims. Taking to Twitter, she wrote: "@MissKatiePrice great work by a journo again way off mark, no stroppy, no fallout, no dramas me and @misskatieprice are laughing at his work" Katie stayed silent, but retweeted Kerry's statement.
After meeting on I'm a Celebrity… Get Me Out Of Here in 2004, Kerry was bridesmaid at Katie's wedding to her now ex husband Peter Andre.
But the two of them had a very public spat when Kerry got into a relationship with Mark Croft, after Katie slammed him.
Earlier this year though, they kissed and made up – posting a selfie together on Twitter to prove it.
