Kim Kardashian, take a bow.
She's just delivered the ultimate take-down of Taylor Swift, releasing evidence proving the singer lied about her knowledge of Kanye West's song Famous.
Even Swift has acknowledged she's been caught out by the reality star, posting this message on social media.
When West released the controversial track earlier this year, with the lyrics "I feel like me and Taylor might still have sex. Why? I made that b**** famous", the internet exploded with support for Swift, including many of her famous pals.
West immediately justified the lines, insisting the Bad Blood singer knew all about it beforehand and had given him approval.
Then, it appears Swift threw him under the bus.
Her rep released this statement at the time: "Kanye did not call for approval, but to ask Taylor to release his single Famous on her Twitter account. She declined and cautioned him about releasing a song with such a strong misogynistic message. Taylor was never made aware of the actual lyric, 'I made that b**** famous.'"
Swift even went so far as to deliver a thinly-veiled jab at West in her Grammys speech.
Now, Kardashian has posted a video on Snapchat, showing a friendly conversation between West and Swift where they discuss the lyrics, and Swift is clearly fine with it, actually thanking him, "I just really appreciate the heads-up, it's so nice. I just really appreciate it."
She even jokes that it's a "compliment."
But is this really the final nail in the coffin for Swift's reign, or an unbelievably well-packaged media stunt dreamt up by the PR machine behind the Kardashians?
Certainly, the timing seems fishy.
Just last night on Keeping Up With The Kardashians (which was filmed months ago), Kim brought up the Taylor Swift/Famous saga, maintaining the story about West getting the singer's approval beforehand, and revealing she had proof to back it up.
