Reality TV star Kristin Cavallari and Chicago Bears quarterback Jay Cutler have called off their three month old engagement. The couple had been together since 10 months and got engaged in April.

"She got dumped. She's absolutely devastated by the breakup,” a source told People.

The couple who got engaged in April was planning a spring wedding; they even completed their wedding registry.

"She was planning her dream wedding, the date was set, the location - everything was set," the source added.

Cutler, 28, on Monday confirmed their split on his Facebook page by writing: "Thank you all for the support, but if you talk bad about Kristin I will delete and block you."

Cavallari, 24, celebrated her wedding with an engagement party last Saturday and later tweeted: "Thx to all my amazing friends for making my engagement party a blast last night!"

Sources told E! Online that the couples were at odds over some issues.

The reality star was spotted up at West Hollywood hotspot The Beverly Lounge on Saturday without her engagement ring.

Cavallari was found hanging out with girlfriends at the VIP table with Nicky Hilton and supermodel Alessandra Ambrosio.
