After spending 10 months together, Kristin Cavallari and beau Jay Cutler have called off their upcoming nuptials.
A source tells PEOPLE Magazine, "She got dumped. She's absolutely devastated. She can't believe this is happening."
The couple, who became engaged this past April were planning a wedding for next spring. "She was planning her dream wedding, the date was set, the location – everything was set," the source says. "She's in shock that the dream wedding she was planning is going to end this way."
Last night at The Beverly Nightclub, Kristin "was hanging out at a table with Nicky Hilton and Alessandra Ambrosio. She was telling friends how they called off the engagement."
Cavallari's rep had no comment.
