Jamie Lynn SpearsBritney Spears reportedly started rumours that little sister Jamie Lynn Spears had been dumped by boyfriend Casey Aldridge.

According to In Touch Weekly, Britney told friends that Casey had dumped the 16 year old mum-to-be because he is “convinced Jamie Lynn is lying” about the paternity of the unborn baby. The magazine claims she said: “He wants a paternity test” and he “doesn’t want to be with her until he’s sure that he’s the father.”

However another source close to the Zoey 101 star has said the rumours are “completely false” and he is satisfied that he is the father.

Earlier rumours claimed Jamie Lynn had been involved with an older executive from her Nickelodeon television series but Casey had been fingered as the dad to avoid the other man being liable for statutory rape charges as Jamie Lynn is under the age of consent. Casey is likely to avoid legal action as he is less than two years older than Jamie Lynn and there is typically a close-in-age exemption for partners with less than a three year age gap.
