While Kim Kardashian was celebrating her upcoming wedding this weekend in Las Vegas, another celeb couple was calling theirs off.
Kristin Cavallari and Jay Cutler have reportedly called off their engagement and ended their 10 month romance ... and Kristin is in shock.
According to PEOPLE, Cavallari had a date and location set -- and, as we previously reported, the two already registered for gifts. Kristin also had her engagement party last week.
Cavallari reportedly stepped out on Saturday without her ring and was seen telling friends the engagement was off. No reason has been given.
The two got engaged while on vacation in Mexico back in April.
