Kim Zolciak doesn’t seem too bothered by whatever’s going on in ex Kroy Biermann’s personal life … because she’s fully locked in on her own romance these days

Check out the pics — Kim was spotted packing on the PDA with boyfriend Kyle Mowitz during a romantic Mother’s Day dinner Sunday … leaning in for kisses and looking completely wrapped up in each other.

The two looked totally inseparable throughout the dinner … getting cozy, exchanging affectionate looks, and acting like they were the only two people at the restaurant. Except they weren’t!

Kim’s kids were also there for the Mother’s Day outing … which makes sense given her happy vibe. We know her kids are her world as she once iconically said, “If my girls are happy, then I don’t give a f***.”

Meanwhile, Kroy appears to be doing just fine himself — with TMZ showing pics of him getting cozy with Jillian Green just the day before … who just so happens to be Kyle’s ex.
