The 35-year-old reality star defends her comments about the 26-year-old pop singer in a preview for Sunday's episode of Keeping Up with the Kardashians.
Kardashian's husband, Kanye West, who famously grabbed the microphone from Swift as she was accepting the award for Best Female Video at the MTV Video Music Awards in 2009 -- leading President Barack Obama to refer to him as a "jackass" -- targeted Swift this year in his song "Famous," which included the lyrics: "I feel like me and Taylor Swift might still have sex. Why? I made that [expletive] famous."
The lyrics immediately caused controversy upon the song's release. West responded by claiming Swift "gave her blessings" to the song, which her rep later denied.
In the GQ interview, Kardashian accused Swift of lying, saying the singer "totally approved" the "Famous" lyrics. She also claimed to have a video of the conversation between West and Swift.
"[Taylor said], 'As soon as I get on that Grammy red carpet, I'm going to tell all the press I was in on it,'" Kardashian said on Keeping Up with the Kardashians. "Just another way to play the victim. Definitely got her a lot of attention the first time."
"I never talk [expletive] about anyone publicly, like, especially in interviews, but I was just, like, 'I've so had it,'" Kardashian tells sister Kourtney Kardashian. "I just felt, like, I wanted to defend him in it."
"I feel like I've had it with people blatantly treating my husband a certain way and making him look a certain way," Kardashian explains. "At this point, I really don't give a [expletive], so I'll do whatever to protect my husband."
Swift referenced West during her 2016 Grammys acceptance speech, calling out those "who will try to undercut your success or take credit for your accomplishments or your fame."
