Britney, who recently hinted at a future including marriage and kids with her former manager boyfriend, dragged Trawick on stage for the dance in front of a select group of celeb bloggers. The performance was a run-through for what will be a featured part of the Femme Fatale show for one very lucky Britney fan.
Brit's 'Femme Fatale' track 'How I Roll' was playing, while she tied him to a chair and straddled him as she performed. Britney's dad and her two sons, Sean and Jayden, were also in the audience for the apparently not-so-private sexy show.
Britney's 22-song set Femme Fatale tour opens this Thursday (June 16) in Sacramento, Calif.
