The 33-year-old TV star - who announced she was divorcing former NFL player Jay Cutler in April - was pictured kissing Jeff at a bar in Chicago, TMZ reports.

The 37-year-old comedian is the host of 'Jeff Dye's Friendship Podcast' and was also a finalist on 'Last Comic Standing' back in 2008.

Despite their public kiss, neither Kristin - who has Camden, eight, Jaxon, six, and Saylor, four, with her estranged husband - or Jeff have made any public comment about their relationship status.

Kristin has, however, recently discussed her separation from Jay, admitting that their marriage had been on the rocks for years.

The blonde beauty also confessed that she'd made a concerted effort to keep their private troubles hidden from the public.

Speaking in September, Kristin - who married the former sports star in 2013 - added: "I'm not interested in anybody right now. I'm happy. I just got out of a ten-year relationship.

"I don't really want to put energy into anything else right now, other than my kids and [her business] Uncommon James and my friends."

Kristin also insisted she doesn't have any plans to appear in her own reality TV series.

The star admitted her life has become "fairly boring" in recent times - but she still enjoys herself.

Asked about making another reality series, Kristin - who previously cancelled 'Very Cavallari' after three seasons - said: "I don't think I'll do a reality show again.

"I'm happy taking my kids to school in the morning, going to the office and then coming home and cooking dinner. Rinse and repeat - my life is fairly boring, but I kind of like it!"
