Was Jay Cutler Too Controlling for Kristin Cavallari? [PHOTOS]

Jay Cutler, 28, may had dumped Kristin Cavallari, 24, but a friend of the "Hills" start told People.com that the Chicago Bear quarterback was too controlling in the relationship.

"Jay Cutler was beyond controlling and didn't really like Kristin to go out," the friend told People.com. "When she did go out, he called all the time and demanded to know exactly where she was going and who she was with."

Cavallari and Cutler were planning to marry next April. Cavallari just announced her engagement to the back in April.

It is also being reported that Cutler made it very difficult for the reality TV star prior to breaking off the engagement.

US Weekly reported that Cutler confirmed the split himself early Monday via his Facebook page.

"Thank you all for the support, but if you talk bad about Kristin I will delete and block you," he wrote, according to Us Weekly, who also reported that the athlete changed his profile picture from one of him and Cavallari to one of him and his sister, Jenna.

Cavallari is said to be "absolutely devastated. She can't believe this is happening."
