Travis Barker's ex-wife Shanna Moakler seemingly shaded him and his new girlfriend, Kourtney Kardashian, on social media.

The pageant winner doesn't seem too happy with the fact that they share so many PDA-filled photos on Instagram.

Moakler, 46, made her feelings known after she posted her own photo on Instagram of her on-again-off-again boyfriend Matthew Rondeau kissing her hand.

One negative commenter wrote, "Girl don't post him when he isn't [posting] you. It's embarrassing."

Moakler clapped back, "Unlike some people my relationship status isn't based on social media posting," she wrote slyly. 'I'm happy on life not on IG...'"

Barker, 45, and Kardashian, 42, have been documenting their relationship over the past few months with a number of intimate posts.

Most recently, Kardashian posted a nearly nude photo of herself embracing Barker in the desert. She wore nothing but a nude-colored thong bikini and a skull print scarf atop her ahead.
