During a 2009 interview that's recently resurfaced, Kim not only showed major love for Taylor, but referred to herself as one of the singer's biggest fans.
"I love Taylor Swift. I'm the biggest Taylor Swift fan," Kim told Entertainment Tonight. "I'm watching her on Twitter. I just signed up for Twitter and I'm watching you, Taylor! Following."
Ironic, right? It looks like Taylor was one of the first people Kim ever followed on Twitter, but now the two use social media to take shots at each other.
