Kristin Cavallari has handed back her engagement ring
The former `Hills` star was dumped by her NFL player fiance Jay Cutler last month even though they were busily preparing for a spring wedding next year and friends say Jay had been thinking about the split for some time.
A source told Life & Style: "She noticed a change in him. He suddenly became more supportive of her career. Up till then, he`d always talked about it coming to an end once they got married. It was like Jay knew he was leaving the relationship and didn`t want Kristin to miss out on great opportunities in Los Angeles."
Kristin - who dated Chicago Bears quarterback Jay for 10 months before they got engaged - recovered from the split by spending a night being comforted by pals heiress Nicky Hilton and model Alessandra Ambrosio at The Beverly in Los Angeles, where she was spotted without her engagementring.
An onlooker said: "She was hanging out at a table with Nicky Hilton and Alessandra Ambrosio. She was telling friends how they called off the engagement."
The shock break-up came just a week after they held a party to celebrate their upcoming nuptials with Kristin tweeting: "Thx to all my amazing friends for making my engagement party a blast last night! (sic)"
Kristin has previously dated `Laguna Beach` co-star Stephen Colletti and Brody Jenner, who she starred with in `The Hills`.
