This comes as Barker's ex-wife Shanna Moakler allegedly accused the Blink 182 drummer of having an affair with Kim which is why she "divorced him" according to a screenshot of a message allegedly from Moakler which was shared on their daughter, Alabama's, Instagram Story.
"Now he’s in love with her sister [Kourtney Kardashian]…It’s all gross…I’m not the bad guy!" Moakler wrote in the purported message.
"I was 'bffs' with Kim Kardashian during a fourth [of July]. She was hooking up with Travis Barker and we were at his house.. he was really dope," O’Day, reportedly wrote on her Instagram Story in July 2020, according to Perez Hilton.
The 37-year-old continued, "Shanna his ex (who I love) supposedly was threatening to slash [Kim’s] tires (sorry girl but that was funny s**t, I would have too) so they asked her to park her car somewhere else."
O'Day detailed "some bs celeb Malibu parties" where Kim allegedly wanted to be photographed and O'Day "had to run around house after house in an uncomfortable dress and high heels to appease that. She got all her photos with celebrities accomplished and we headed back to Calabasas."
O'Day said she was "super annoyed that we had to do all of that because I absolutely LOVE fireworks and I have always been in memorable places watching them every year. Because we had to chase clout extra hard we got on [the] freeway late and ended up in her Range Rover as the fireworks started."
O'Day said she asked Kim if they could pull up on the road and watch the fireworks. "And she turned to me and said: you know last year on the fourth I was on a yacht with Paris Hilton in the middle of some remote beautiful place … and this year I’m sitting on a plot of grass in calabasas with you.' Hahahaha. I was like, oh.. cool," O'Day concluded.
This comes after sources told Page Six that Barker and Kim did not have an affair. "Travis and Kim have never had a romantic relationship," an insider told the outlet. "They were friends who met through Paris Hilton and that is also how Kourtney and Travis were introduced."
Another insider said it was a "shame" that Moakler "continues to spread lies because she is clearly bitter her ex is happy and has moved on."
There was also speculation after an interview Barker did with Us Weekly in 2015 resurfaced where he said Kim was "eye candy" and "couldn’t keep my eyes off Kim." However, insiders said that the 45-year-old was "joking."
"Anyone who is close to them has always known that Travis has been in love with Kourtney for forever [not Kim]," a source said. "They are madly in love and best of friends. Everyone in their circle couldn’t be happier for them."
Barker and Kourtney have been linked since early this year.
