\nThe 17-year-old actress\u2019s relationship was been rocked by claims that Casey Aldridge, 19, had been having an affair with Kelli Dawson, 28.
\nAfter the revelations last week, the Zoey 101 star and her two-month-old daughter Maddie Briann have fled the couple\u2019s home in Mississippi to stay with her mother Lynne 30 miles away in Louisiana.
\nPictured for the first time since the reports, Jamie Lynn looked miserable as she joined mother Lynne and baby Maddie to buy a new mobile phone in a store in her hometown of Kentwood.
\nDressed for the hot weather in a denim mini skirt and white vest, Jamie Lynn was still wearing the engagement ring she accepted from Casey in March – just three months before their daughter was born.
\nThe couple, who have been dating for two years, were expecting to wed later this year, but their marriage plans have been thrown into jeopardy following the recent reports.
\nKelli told America\u2019s 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.
\nKelli told the publication: \u2018I see him all the time, at least once a week.\u2019 She claims she stopped sleeping with Casey towards the end of Jamie Lynn\u2019s pregnancy.
\nShe said: \u2018It just didn\u2019t feel right. He had to deal with the baby coming, and it had to stop.\u2019
\nBritney\u2019s first husband Jason Alexander, who still lives in the Spears\u2019 family hometown, supported Kelli\u2019s claims. He said: \u2018Kelli and Casey have been a couple on and off for a few years. \u2018They were a really tight couple, but I think it was hard for Kelli, having Jamie Lynn in the picture.\u2019
\nCasey has denied the allegations, accusing his ex-girlfriend of fabricating the affair to make money. If Jamie Lynn needs lovelife advice, she can turn to older sister Britney, who has two failed marriages behind her. She is currently getting her career back on track after a tumultuous two years following the collapse of her two year marriage to aspiring rapper Kevin Federline.<\/p>\n","protected":false},"excerpt":{"rendered":"
