Brit certainly loves dating her staffers! He's the mystery man "Extra" spotted videotaping Spears -- and the same musclebound hunk snapped tangoing with a bikini-clad Brit in Cabo. Now the pop princess has fallen for a man known only as "Lee," her hunkish bodyguard of six months.

Britney's habit of dating her male employees isn't new -- she married back-up dancer K-Fed and is rumored to have had a fling with ex-manager Sam Lutfi, and paparazzo Adnan Ghalib is said to have staged various photos.

In other Britney news, "Extra" has learned that her conservatorship has been extended through December 31st. Britney reluctantly signed papers extending the conservatorship -- which has already cost her $200,000 in attorney fees. Also, Brit's dad and Sam Lufti have reached a private agreement, there is no hearing or order -- Mr. Spears asked that the temporary restraining order be dismissed from the calendar, and the judge agreed.
