Wedding bells will reportedly soon be in the air for Britney Spears and her fiance Jason Trawick. A source close to the pop star revealed that the pair are planning to tie the knot within weeks of finishing up her duties as an X Factor judge.

"She’s put a treadmill into her X Factor dressing room and is making sure she’s jogging as often as she can. She’s taking her look incredibly seriously and has said she will dazzle with her outfits and her body on the live finals of X Factor. It’s very much a countdown to the nuptials right now… We’re talking within weeks," the source said.

Hopefully the third time is the charm for the 30 year-old, as the upcoming wedding to Jason comes after her 55-hour marriage to her childhood sweetheart Jason Alexander and the subsequent two-year marriage to Kevin Federline, with whom she has two sons.

The season finale of The X Factor is set to air in November.
