Kristin Cavallari is remaining coy about rumours she has rekindled her romance with ex-fiancee Jay Cutler.

The former 'Laguna Beach: The Real Orange County' star was cheered on by the Chicago Bears quarterback - who she separated from in July - when she took to the dancefloor with her professional partner Mark Ballas on 'Dancing With The Stars' on Monday night (03.10.11).

The cameras kept on panning to Jay after their performance but Kristin was remaining tight-lipped on whether she had invited her former beau to the show.

She said: "I have nothing to do with that. I don't direct where the camera goes."

The 24-year-old beauty dated Jay for eight months before they got engaged in April 2011 before he called it off in the summer.

Although Kristin and Mark earned a score of 24 out of 30 for their rumba, the pair were voted off the programme last night (04.10.11).
