Kristin Cavallari has moved swiftly to shoot down rumours she is once again engaged to injured American football star Jay Cutler.
The reality TV star was reported to have reconciled with the Chicago Bears quarterback, who broke his thumb in Sunday's (20Nov11) game with the San Diego Chargers, and accepted a second proposal from him.
But Cavallari has taken to her Twitter.com page to dismiss the speculation.
She writes, "New week new rumor. I'm not engaged u guys."
Cavallari and Cutler were originally set to marry next summer (12) but they called off their engagement in July (11).
