Jamie Lynn Spears fiance affair

Jamie Lynn Spears goes home to mum after fiancé affair rumours

Jamie Lynn Spears has gone to stay with her mum after revelations that her fiancé Casey Aldridge has had an affair.

The new 17-year-old mum took her two-month-old daughter, Maddie Brian, from the couple's home in Mississippi to mother Lynne's house 30 miles away in Louisiana, following the news that Casey had been having an affair with 28-year-old Kelli Dawson.

Pictured out yesterday with her mum, Jamie was still wearing the engagement ring given to her by Aldridge just three months before she gave birth.

The couple, who have been dating for two years, were planning to wed this year, but the relationship has been rocked by Kelli's revelations. She told America's InTouch Weekly magazine she had been dating Casey since November 2006, and had still been seeing him when Jamie Lynn was six months pregnant with Maddie - the same month he proposed.

She told the magazine: 'I see him all the time, at least once a week.' But she claims she stopped sleeping with Casey towards the end of Jamie Lynn's pregnancy, adding: 'It just didn’t feel right. He had to deal with the baby coming, and it had to stop.'

Casey denies the claims and has accused Kelli of fabricating the story to make money.

But fellow Kentwood resident – and Jamie's sister Britney Spears' ex-husband – Jason Alexander – supports Kelli's claims.

He said: 'Kelli and Casey have been a couple on and off for a few years.

'They were a really tight couple, but I think it was hard for Kelli, having Jamie Lynn in the picture.'
