The reality TV star announced the engagement Wednesday on her Twitter feed, saying: "This time its official..Jay and I are engaged again :)." And the Chicago Bears' quarterback confirmed the news to reporters a short time later.
During a news conference that focused mainly on his recovery from a broken right thumb, Cutler jokingly said he "just heard about" Cavallari's post from earlier in the day before acknowledging they're engaged. He said they haven't set a wedding date.
Cutler broke off their engagement shortly before they were to marry last summer.
Cavallari became a celebrity in 2004 when MTV tracked her high school love life and rivalry with Lauren Conrad. She was later on "The Hills" and was a contestant this season on "Dancing With the Stars."
