It appears Lynne Spears was onto something when she questioned whether or not Justin Timberlake was daughter Britney Spears’ first sexual partner in her new memoir, Through The Storm.

A man who says he was the first person to experience Spears’ womanhood has stepped forward to spill the beans on the young lovers’ high school romance.

Former teen football star Reg Jones, 30, says he slept with Britney when he was seventeen and she only fourteen.

“We were madly in love and Britney was very passionate. I’d often stay over at her house and we’d fool around like any young couple,” Reg said in an interview with Daily Mirror on Friday.

“Although there was a couple of years difference in our age, it didn’t seem to matter.”

He says he was heartbroken when the “Gimme More” star dumped him for Justin Timberlake.

“She was everything a boy could have wanted - great-looking, always laughing and liked by everyone.”

It sounds as if Reg could still be holding a torch for the one that got away, he admits he still thinks of the pop star and has hung on to a photograph of her wearing a black bra.
