Reality TV star Kristin Cavallari is back in the arms of her former fiance two months after they called off their engagement and split.

Sources tell People.com Cavallari is "working out" things with Chicago Bears quarterback Jay Cutler.

The insider says, "They're not officially back together but they're definitely talking and figuring things out... They're taking things slow (and) they're talking a lot."

And Cavallari made it clear Cutler's in her thoughts - she tweeted a picture of herself sporting a Bears sweatshirt on Sunday, as Cutler and his teammates battled the Green Bay Packers.
