Britney Spears has teased she is ready to marry Charlie Ebersol.

The 33-year-old singer - who was previously wed to Kevin Federline for just over two years and had a marriage to Jason Alexander annulled 55 hours after they tied the knot in Las Vegas - is smitten with her boyfriend of five months and could be ready to take their romance to the next level.

She gushed: ''I'm very blessed to have him as a part of my life, that's very cool.''

And asked by 'Extra' special correspondent Pauly D if they could head down the aisle at a Las Vegas chapel close to where she has her 'Piece of Me' concert residency, she laughed and said: ''You never know.''

The 'Toxic' singer - who has sons Sean Preston, nine, and Jayden, eight, with Kevin - donned an 'I love Charlie' vest for a recent Las Vegas show and admitted her boyfriend was touched by the gesture.

She said: ''He said, 'You're the sweetest girlfriend in the whole world,' he was really happy I did that.''

Charlie - whose parents are NBC executive Dick Ebersol and actress Susan Saint James - recently said he and Britney are ''homebodies'' and credited their love of ''centering back'' home to making their relationship work amongst their bust schedules.

He said: ''The thing that I learned from my parents was no matter how busy you are, home base is the single most important thing. As long as you're centering back to home base and that's the strongest magnet in your life, that everything else is OK.''
