Shanna Moakler recently accused Travis Barker of 'parental alienation'

Moakler, Barker's mother, opened up about her tense co-parenting relationship with ex-husband Travis Barker during an appearance on the "Dumb Blonde" podcast earlier this month. Moakler told host Bunnie XO her child were "enamored" with the Kardashian family's fame when they criticized her parenting.

"When Travis got with Kourtney, there was some parental alienation going on there," Moakler said. "Travis — even when we weren't together — always wanted to be the super dad: 'I'm the best parent. I'm the this and that,' and I'm like, 'Bro, you win.' Like, you're the winner here. You have all the money, and you have all this."

Moakler told Bunnie XO she "removed" herself "so that (the Kardashians) couldn't bond with my children over hating me."

"Go do what you need to do and when you're ready, I will be here loving you unconditionally," Moakler said of her approach. "And I will be here as your mother, and I will wait. And that's what I did."
