Taylor Swift is finally opening up about her feud with Kim Kardashian, revealing how "low" it left her feeling.

Speaking with Elle magazine, the 29-year-old singer shared a secret about "disarming someone's petty bullying," telling readers it "can be as simple as learning to laugh." Swift added that "bullies want to be feared and taken seriously," before discussing a targeted attack on her from someone that inspired others to get "on board."

"A few years ago, someone started an online hate campaign by calling me a snake on the internet. The fact that so many people jumped on board with it led me to feeling lower than I've ever felt in my life," she said of her feud with Kardashian. "It would be nice if we could get an apology from people who bully us, but maybe all I'll ever get is the satisfaction of knowing I could survive it, and thrive in spite of it."

After the online attack, Swift decided to make it part of her act. She introduced a giant inflatable snake named Karyn into her act, bringing it out when she performed "Look What You Made Me Do," which is believed to be about Kardashian and Kanye West.

"I can't tell you how hard I had to keep from laughing every time my 63-foot inflatable cobra named Karyn appeared onstage in front of 60,000 screaming fans," she said. "It's the Stadium Tour equivalent of responding to a troll's hateful Instagram comment with 'lol.'"

Swift's drama with Kardashian started in July 2016, when the Keeping Up With the Kardashians star posted a Snapchat video of Swift chatting with her husband about a lyric in his song "Famous." In the song, West, 41, raps: "I feel like me and Taylor might still have sex / Why? I made that b---- famous." Kardashian then called Swift a snake on Twitter.

Swift maintained that while West contacted her about using her name in the song, he did not tell her he'd refer to her as "that b----" in it. She was hurt by the line, and fired back on Instagram with a statement.

"I would very much like to be excluded from this narrative, one that I have never asked to be a part of, since 2009," she wrote.
