Britney Spears' parents have reportedly slapped a six-month sex ban on their daughter to prevent any bumps in the road on her way back to the top.

Fiercely protective Jamie and Lynne Spears feel that Britney's downfall was linked to the men in her life and want their daughter to refrain from any male contact for a while.

With two failed marriages, a relationship with paparazzo Adnan Ghalib and reports of a supposed sex tape, the troubled star's questionable taste in men has often come back to haunt her.  

A friend tells Now, “Jamie and Lynne feel she’s so close to cracking the big time again that they don’t want anything to get in her way.

“They’re desperate to ensure that it won’t happen again. Their worst nightmare is that she gets involved with someone else who’s just trying to use her for her money or to further their own career.”

Britney's dad already has control over her financial assets until December - whether he can do the same with her sexual habits remains to be seen.
