Kim Kardashian West is clearly not afraid to defend her husband, Kanye West.
A source close to the 35-year-old reality star tells ET that Kim has no regrets after posting bombshell videos on Sunday night of Kanye talking to Taylor about his song, "Famous," prior to its release -- even at the risk of Taylor filing a lawsuit for being recorded without her consent.
"Kim doesn't care. She doesn't regret it," the source says.
In the edited conversation Kim shared to Snapchat, Kanye and Taylor are heard discussing the lyric, "For all my south side n****s that know me best / feel like me and Taylor might still have sex" and not the most contested line, "Why? Because I made that b**ch famous."
"The decision to post the video on Snapchat was decided by Kim last minute. It's not something she premeditated," the source continues. "This was a decision that was made by Kim and really not influenced by Kanye at all. She just felt it was time that people saw that Kanye did everything he could do to make sure Taylor had known about this and that she felt comfortable about it, and she essentially gave him approval."
Taylor denies that she ever granted her permission -- noting "you cannot ‘approve’ a song you haven’t heard" in a statement on Sunday night. "Being falsely painted as a liar when I was never given the full story or played any part of the song is character assassination," she added.
According to the source, Kim's decision to release the tapes of Kanye reaching out to Taylor for permission was largely fueled by Taylor's widely praised acceptance speech for Album of the Year at the GRAMMYs in February, in which the "Shake It Off" singer took not so subtle jabs at Kanye.
Not surprisingly, our source says Kim took great offense to the highly publicized moment.
"She gets up on that stage and, essentially, dedicates her entire speech to slamming Kanye. And no reference to 'that b**ch' was made," the source says. "And that's exactly why Kim released it. It stemmed all the way back from that GRAMMYs speech -- when Taylor went out of her way at the GRAMMYs and said that 'no one made me famous' in so many words."
The source also claims that Kanye attempted to reach out to Taylor in February when he first learned she was upset with the lyrics, though the two did not speak.
"Kim's perspective is: 'Taylor, why would you set him up to fail?'" the source says. "What happened in 2009 [Kanye infamously interrupting Taylor at the MTV Video Music Awards] was a mistake. Kanye is aware of that and he apologized for that mistake. But what happened this year was not a mistake. She's sick of it all."
According to our source, Kim's inner circle is "proud" of the reality star for the bold move.
While Kim's decision to leak parts of the phone call may have been last minute, the reality superstar was clearly thinking about the feud beforehand. The mother of two called out Taylor in an interview last month with GQ, when she first brought up the existence of the tapes. Sunday's episode of Keeping Up With the Kardashians was also heavily dedicated to the he-said/she-said war of words between Kanye and Taylor.
Kim tweeted on Sunday, "There's a BIG difference between shading someone and speaking the truth!"
And not everyone is Team Kardashian. A few of Taylor's pals took to social media to defend the 26-year-old singer after the hashtag #KimExposedTaylorParty quickly started trending.
"There are more important things to talk about," Taylor's bestie, Selena Gomez, tweeted minutes after Kim's clips were posted. "Truth is last thing we need right now is hate, in any form. This industry is so disappointing yet the most influential smh."
