Did Kourtney Kardashian shade Travis Barker’s ex-wife through Poosh?

The claws are out.

Fans are convinced that Kourtney Kardashian stealthily shaded new boyfriend Travis Barker’s ex-wife Shanna Moakler with one of her Poosh blog posts.

Last week, Moakler seemingly made her feelings on Barker’s new relationship clear by “liking” a comment on Instagram saying that Barker “downgraded big time.”

Soon after her shady “like,” Moakler went one step further and posted a message to her Instagram story on Monday that read, “Stop complaining about your life. There are people out there dating your ex.”

Now it seems 41-year-old Kardashian isn’t going to take any apparent disses sitting down.

Kardashian put up a Poosh blog post titled, “How to Break the Habit of Stalking Your Ex on Social Media.”

“Modern life has cursed us. We are haunted by the radical accessibility of everyone we’ve ever met, hooked up with, or dated via a tiny device we happen to keep on our person during all our waking moments,” the blog post stated. “It’s no wonder we’ve made a daily—or several times daily, or every hour—habit of checking in our exes, and our exes’ exes, their new lovers, friends, acquaintances, and so forth. It’s not healthy, it’s not helping us move on, and unfortunately, it’s all too easy.”

Is she trying to teach Moakler a lesson? Only time will tell.

Despite Moakler’s actions on social media, she says she’s happy for Barker and Kardashian.

“He’s my friend and co-parent, and I want him to be happy,” she previously said, “and if being with her makes him happy, and she’s happy, I’m happy for both of them, honestly.”

Barker, 45, and Moakler, 45, got married in 2004 but finalized their divorce four years later. They continue to co-parent their two kids: 17-year-old son Landon and 15-year-old daughter Alabama.

The Blink-182 rocker and Kardashian went Instagram-official last week, just days after spending Valentine’s Day together.

Page Six confirmed that the duo, who have been friends for years, started seeing each other romantically in January after they both posted pics from Kris Jenner’s Palm Springs vacation home.

Kardashian has three children with ex Scott Disick: 11-year-old son Mason, 8-year-old daughter Penelope and 6-year-old son Reign.

Barker was also married to Melissa Kennedy from 2001 to 2002.
