Spears has allegedly started a countdown to her big day...
According to The Mirror, the pop princess has begun a 'countdown' to her big day, with the nuptials expected to take place once her judging duties on the panel come to an end.
A source told the newspaper: "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."
They added: "It's very much a countdown to the nuptials right now... we're talking within weeks."
Trawick - who proposed to Spears last year - recently revealed to ELLE magazine that it was the Hold It Against Me singer who 'made the first move' in their romance.
