The former Laguna Beach star broke the happy news on Twitter on Wednesday, telling her followers, "This time its official..Jay and I are engaged again :)."
After 10 months attached at the hip, the couple shocked everyone with the breakup over the summer and even returned wedding gifts to well-wishers that had already been bought from their registry.
The reunion was less of a surprise than the break-up after Kristin was spotted wearing her sparkly engagement ring on Tuesday night while having dinner at Le Petit Four in Los Angeles.
As RadarOnline.com previously reported, the pretty pair sparked rumors of a reuinion in early October when they walked hand-in-hand together after a romantic breakfast.
The early rendezvous came the morning after NFL star Cutler sat front and center in the audience cheering Kristin on during her Dancing With The Stars performance.
The couple had hinted on Twitter over recent weeks that they might be getting hot and heavy again. On November 11, Cutler tweeted, "Dinner date night with @KristinCav. She loves her creamed spinach."
Before the Bears’ November 9 game against the Philadelphia Eagles Cavallari tweeted: "To the man with the best butt in football, good luck tonight."
Unfortunately for his teammates, Cutler has plenty of free time to spend with his fiancée as he is currently nursing a broken thumb and unable to play football.
