Brody Jenner and Kaitlynn Carter Co-Parenting Dogs, Not Back Together

Brody Jenner and Kaitlynn Carter may SEEM like they’re rekindling a lost romance, but they’re not getting back together … instead, they’re just co-parenting pooches.

Here’s the deal … fans have noticed Brody and Kaitlynn lookin’ pretty chummy recently — BJ was the muscular hunk in the reflection of one of KC’s snaps, and they both posted similar photos from the same beach — but we’ve learned there’s nothing brewing, other than a new dog in the mix.

Sources close to the famous exes tell TMZ … Brody and Kaitlynn have hung out and bumped into each other a few times, but it’s NOT a sign they’re getting back together.

When Brody and Kaitlynn were “married” — it was never a real marriage, there was a ceremony in Indonesia but they never made it legal — they shared 3 dogs together … Radar, Tank and Shoey.

Our sources say Brody and Kaitlynn had an agreement when they split … he would take the dogs full time, and she had visiting rights.

We’re told Kaitlynn adopted a new dog, Dash, a couple months ago and wanted to introduce the pup to the pooches she co-parents with Brody, so the exes set up a meet-and-greet for the dogs.

They all hit it off — the dogs, not Brody and Kaitlynn — freaking out and playing like good boys and girls.

Brody and Kaitlynn are getting along too … we’re told they said hello and were friendly when the bumped into each other at the beach in Malibu, in what sources say was not a scheduled hangout.

The exes are both moving on, but we’re told there’s no bad blood … Brody was spotted quarantining with a UCSB grad and witnesses say Kaitlynn went on a date this week with Amber Heard‘s ex, Kristopher Brock.
