Katie Price claims she is divorcing Kieran Hayler.

The former glamour model - who recently announced she is pregnant with her fifth child, her second with the stripper - has accused her spouse of having an affair with her friend and now wants to end their marriage.

She tweeted: ''Sorry to say me and kieran are divorcing him and my best friend jane pountney bee having a full blown sexual affair for 7 months (sic)''

The couple - who have eight-month-old son Jett together - married in January 2013 after just a few months of dating.

Katie - who also has children Harvey, 11, Junior, eight, and Princess, six, from previous relationships - gushed earlier this week about how she is happier than ever with Kieran.

She told Now magazine: ''I've never been this happy with anyone before. With me and Kieran it's all about the kids and being together and just having a family. I'm much more chilled - I haven't even had mad pregnancy hormones so I think that must be down to the fact he makes me so happy. He's been with me at the worst times when Jett was born and we thought we'd lose him and then he's been through this. He's a good man.''
