Kelly Clarkson, Kellie Pickler Take Aim At Kanye West's VMA Outburst

Mary-Kate Olsen and 'Hills' star Spencer Pratt also come to Taylor Swift's defense.

It's no surprise "Kanye's" and "#teamtaylor" are among Twitter's top 10 trending topics early Monday morning (September 14) following Kanye West's outburst at the Video Music Awards, where he interrupted Taylor Swift's acceptance speech for Best Female Video to protest on behalf of Beyoncé.

In addition to the outcry of fan support for Swift, fellow celebrities continue to bolster the 19-year-old singer via Twitter and blog messages. The latest celebrity to come to Swift's defense is fellow VMA nominee Kelly Clarkson, who penned an open letter to West on her blog.

"Dear Kanye, what happened to you as a child??" Clarkson wrote. "Did you not get hugged enough?? Something must have happened to make you this way and I think we're all just curious as to what would make a grown man go on national television and make a talented artist, let alone teenager, feel like sh--. I mean, I've seen you do some pretty sh---y things, but you just keep amazing me with your tactless, a--hole ways. It's absolutely fascinating how much I don't like you. I like everyone. I even like my a--hole ex that cheated on me over you ... which is pretty odd since I don't even personally know you. The best part of this evening is that you weren't even up for THIS award and yet you still have a problem with the outcome. Is winning a Moonman that much of a life goal?? You can have mine if it will shut you up. Is it that important, really??

"I was actually nominated in the same category that Taylor won, and I was excited for her ... so why can't you be??" the letter continued. "I'm not even mad at you for being an a--hole ... I just pity you because you're a sad human being. On a side note, Beyoncé has always been a class act and proved again tonight that she still is. Go TEXAS!! Taylor Swift, you outsell him ... that's why he's bitter. You know I love your work! Keep it up girl!"

Immediately following the incident, celebrities like Katy Perry, Pink and Paramore's Haley Williams took to their Twitter accounts to express distaste for the stunt. Swift's close friend, country artist Kellie Pickler, tweeted, "Tator Tot, you handled yourself with Grace. Kanye, go grow some f-ing balls, bi---! don't mess w/my lil sis!!"

Mary-Kate Olsen took a more diplomatic approach, praising Beyoncé for giving Swift the chance to finish her speech. "I'm so glad Beyoncé gave Taylor her moment," Olsen tweeted. "She knows what's best!" "The Hills" star Spencer Pratt acknowledged that even he wouldn't pull a stunt like that. "Let's be very clear: King Spencer would never do anything like what Kanye just did to a sweet soul like Taylor!" Pratt tweeted.
