Kristin Cavallari poses in wedding dress just two days before fiance Jay Cutler ends engagement

Kristin Cavallari is said to be heartbroken after Jay Cutler broke off their engagement.

Call it a case of bad timing! 

Just two days before her engagement with Chicago Bears quarterback Jay Cutler was called off, Kristin Cavallari was glowing with excitement as she posed in a number of wedding dresses.

Unaware of how her life would soon turn upside down, the former "Hills" star was the picture of a blushing bride in a new photo shoot for Life & Style. The 24-year-old gushed about her plans for a traditional wedding and her vision of walking down the aisle in a strapless gown.

"I want a romantic, mystical wedding, with lots of flowers," she told the magazine during the shoot at L.A.'s Mondrian Hotel on July 21.

Though her relationship seemed to be on the right track at the time, an insider close to Cavallari reveals the real problems began the next day.

 When Cutler, 28, asked the blond beauty to fly back to Chicago with him the following morning, she said she wasn't able to because she had work commitments on a new TV project.

Cutler reportedly became upset and "told her that she needed to commit to him, and to move to Chicago," the insider added.

When it became clear that Cavallari had no intention of giving up her career in entertainment, Cutler broke up with her — and returned to Chicago alone on July 23.

 "Kristin really loved Jay," said the source. "She is devastated."

Cavallari and Cutler, who have been together since last August, celebrated their impending nuptials with an engagement party last week. They were set to wed next spring.
