Kristin Cavallari and Jay Cutler, attend the premiere of Summit Entertainment's "Source Code" at the Arclight Cinerama Dome on March 28, 2011 in Los Angeles, California.
Jay Cutler's girlfriend wasted no time putting engagement rumors to rest Monday.
Life & Style magazine reported that Cutler proposed to Kristin Cavallari a second time and that she accepted.
But Cavallari responded via Twitter, saying "New week, new rumor. I'm not engaged u guys."
The rumor comes in the midst of a news cycle already dominated by the Chicago Bears quarterback after he fractured his thumb in Sunday's game, putting the rest of his season in doubt.
The two were originally slated to get married this spring, but Cutler broke things off last July.
In recent months they've appeared to have rekindled the romance, appearing together in public and sending numerous love tweets.
Despite Cavallari's denial, the magazine quotes a source as saying that Cavallari was telling friends that the engagement was back on, she was "over the moon with happiness" and that a new date had not been set.
