Oh what a difference a few months can make for a celebrity couple.

NFL star Jay Cutler has gone from calling off his wedding a few months ago to expecting a special delivery from the stork.

The Chicago Bears quarterback and his off-again, on-again fiancee, Kristin Cavallari, are preparing to welcome a baby into the world.

"She is really happy. She is in the early stages, but she can't wait to be a mom," a source told Us Weekly.

The famous couple confirmed to People magazine they are "thrilled" to announce Cavallari is pregnant.

Just last summer, Cutler and Cavallari abruptly ended their engagement of three months and sent back their wedding gifts. They ended up getting back together in November.

Cavallari, 25, a reality television personality most famous for her work on The Hills, competed on Dancing with the Stars last year. She has purchased a home in Tennessee with Cutler, who attended Vanderbilt in Nashville. The pair plans to start a family in the Volunteer State, according to the tabloid magazine.

On the football field, Cutler, 28, had 13 touchdowns and 7 interceptions to help Chicago start 7-3 during the 2011 season. But broken thumb on his throwing hand in Week 11 against the Chargers ended his season and the Bears failed to make the playoffs.
