Katie Price's best friend has admitted she had an affair with Kieran Hayler.

Jane Pountney, 49, released a statement today (09.05.14) insisting she ''deeply regrets'' her seven-month sexual relationship with the former glamour model's third husband.

The statement, which was released by Jane and her husband Derrick, said: ''It is true that Jane and Kieran Hayler had an affair. This is something that Jane deeply regrets and we will not provide any more details about it.''

The mother of two's ''full blown sexual affair'' with the builder was revealed on Wednesday (07.05.14) when Katie announced she was divorcing the father of her eight-month-old son Jett due to his deceitful actions.

Katie, who has recently discovered she's six months pregnant with Kieran's second child, tweeted at the time: ''Kieran is a disgusting human being doing this after I've just had a baby and still doing it till I caught them

''No human being deserves this especially being 6 months pregnant

''Worse pain in the world (sic)''

The reality TV star - who also has children Harvey, 11, Junior, eight, and Princess, six, from previous relationships - also branded her best pal Jane - who she has known since she was 15 - a ''clone'' and a ''w***e''.

Following her foul-mouthed Twitter tirade, Katie stormed round to her Jane's house in West Sussex for a showdown, before being escorted out three hours later by Derrick.

The blonde beauty later released a statement on her official website, claiming her earlier outburst on the social networking site was a sign of her ''heart breaking''.

Katie married Kieran in January 2013, just a few months after they started dating.
