Taylor Swift's feud with Kanye West worsened when Kim Kardashian weighed in on it in her GQ interview published earlier this month. Things between the two musicians will apparently get nastier in the future as the pop superstar is reportedly readying a diss song aimed at the rapper's reality TV star wife.

According to In Touch, Taylor already wrote some not-so-good things about Kim. "Taylor's already been inspired to write some harsh lyrics [about Kim]. Kim messed with the wrong woman," a source told the magazine.

As fans have known, Kim put Taylor on a blast in the interview for the latest GQ issue which she covered. Speaking of the controversial lyrics on Kanye's song "Famous", the 35-year-old star insisted that her husband called the former country diva and asked for her approval before he put out the track earlier this year.

"She totally approved that. She totally knew that was coming out. She wanted to all of a sudden act like she didn't. I swear, my husband gets so much s**t for things [when] he really was doing proper protocol and even called to get it approved," she said.

In response, Taylor's rep didn't deny that she had a phone conversation with Kanye before "Famous" came out. However, he at the time only asked her if it was okay to release the song through her Twitter account.

Taylor declined the request because she'd never heard the track. "A song cannot be approved if it was never heard. Kanye West never played the song for Taylor Swift," her rep explained. "Taylor heard it for the first time when everyone else did and was humiliated."
