"Kristin is doing great. She is busy with her children and doesn't have much time to date. She enjoys spending time with Jeff, though," the source says.
"They have been on several dates. He makes her laugh and is easy to get along with," the source adds. "She is having a good time with him."
But while the Very Cavallari star, 33, is enjoying her time with 37-year-old Dye, an insider tells PEOPLE that "it’s nothing serious yet" and adds “she is just having fun."
Reps for Cavallari and Dye did not immediately respond to PEOPLE's request for comment.

Days later, a source told PEOPLE that Cavallari was "taking it super slow" with Dye in order to focus on her family.
"It's new, but they've been talking for a while," the source said. "It's not serious. Kristin has her kids and is going through a divorce, and family is still her priority. Jeff is a super cool and funny guy who makes her laugh. She's having fun but taking it super slow."

Her new romance comes six months after Cavallari and the former Chicago Bears quarterback, 37, announced their split in April after seven years together. They share three children: sons Camden, 8, and Jaxon, 6, and daughter Saylor, 4.
Speaking with PEOPLE in September, Cavallari said that dating is "the last thing on my mind right now."
But while she is focusing on herself for the moment, she didn't totally rule out finding love again one day.
"I'm not interested in anybody right now. I'm happy. I just got out of a 10-year relationship," the Laguna Beach alumna said. "I don't really want to put energy into anything else right now, other than my kids and Uncommon James and my friends."
