Chicago Bears quarterback Cutler proposed to the former The Hills star in April (11) while on vacation in Cabo San Lucas, Mexico and the couple celebrated its engagement with a party earlier this month (Jul11).
But People.com claims the young fashionista has been left heartbroken after Cutler broke off the engagement.
A source tells the website, "She got dumped. She's absolutely devastated. She can't believe this is happening... She's in shock that the dream wedding she was planning is going to end this way."
The former couple was said to have set a spring (12) date for its nuptials.
