Kanye West vs Taylor Swift round 2

Kanye West went on another one of his infamous Twitter rants Friday morning and this time, he was attacking Taylor Swift.

West called Swift a "liar" for claiming she knew nothing about the lyrics in his new single, "Famous," in which he claims he made her famous and alludes to the possibility of a sexual encounter with the pop star. In the song, West also calls Swift a (expletive).

West released the song, from his new album, "The Life of Pablo" Thursday night during his fashion show at New York's Madison Square Garden.

According to Yeezy, he "called Taylor and had a hour long convo with her about the line and she thought it was funny and gave her blessings."

However, Swift's spokesperson told ABC News that "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."

The response caused Kanye to launch a 15-tweet tirade. Here are a few of the messages:

We're guessing, T-Swift was able to shake off the tweets because she has not addressed the issue on Twitter.

However, Whataburger decided to get in on the alleged beef.
