When reality starlet Kristin Cavallari
and Chicago Bears quarterback Jay Cutler called off their engagement
in July, the Dancing with the Stars contestant
was "absolutely devastated," a source told PEOPLE at the time.
After a summer apart
, though, a source tells PEOPLE the pair are "working it out."
"They're not officially back together but they're definitely talking and figuring things out," the source says.
The two, who were planning a spring wedding
, got engaged in Mexico in April after dating for seven months.
"Everything happened too fast when they first got together," explains the source. "So this time they're taking things slow."
With Cavallari's Dancing with the Stars
schedule and Cutler's football season underway, the two haven't physically spent time together again yet. But, says the source, "they're talking a lot."
Already back on Team Cutler, Cavallari watched Sunday's Bears game with girlfriends and Tweeted a picture of herself sporting a team sweatshirt.
