Britney Spears might have to lend more focus to her wedding plans as she is reportedly set to marry beau Jason Trawick "within weeks." Spears’ wedding to former manager and current fiance Trawick is allegedly mere weeks away, the Mirror reported on Sunday. “She’s put a treadmill into her ‘X Factor’ dressing room and is making sure she’s jogging as often as she can," a source told the U.K. publication. “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.”
