Kellie Pickler, Taylor SwiftShe once called her Fearless tourmate one of her best friends, but now Kellie Pickler says she barely spends any time anymore with Taylor Swift. "We both are even busier this year than last year," Kellie tells OK! magazine. "You really see each other backstage passing to go onto the stage, and that's about it."

Kellie also claims to have no clue about the young man whom Taylor is currently rumored to be dating. "I don't even know who that is," she says of Glee star Cory Monteith. "I've never seen the show. I don't watch television, and I have no idea."

But could this just be OK! magazine making a mountain out of a molehill? We know it would take a lot to break the blonde beauties' BFF status. "When I say she's like a little sister to me, it's really true because we both keep each other in line," Kellie told The Boot last year. Besides, she could've just been playing coy to protect Taylor's love life from the press!

Still, Taylor isn't the only gal-pal Kellie is spending less time with lately. Once close with fellow 'American Idol' alum, Carrie Underwood, Kellie says she's unsure if she will even attend Carrie's upcoming wedding ceremony. "I don't know," she admits. "I've only spoken to her a few times since she got engaged, but I'm very happy for her. And absolutely, if scheduling works out, I would love to be there."

Blame part of the distance on everyone's crazy schedules, but Kellie also says she stays out-of-touch with celebrity news, and had no idea that her former competitor on 'Idol,' Jennifer Hudson was even engaged. "I don't know anything that's going on in the world. I'm more into politics. I work a lot with the USO, so I focus more of my attention on what I feel is important. I don't know about anyone's personal life, but I wish everyone success, luck and happiness."

Returning from her third USO tour earlier this year, where was joined by buddies Jamey Johnson and Randy Houser, Kellie is in the studio working on the follow-up to her No.1 self-titled album. She may also reunite with her old friends when she competes against both Taylor and Carrie at the upcoming CMT Awards for for Female Video of the Year. She's also nominated with Taylor for Collaborative Video of the Year for a tune they wrote together, 'Best Days of Your Life.' The CMT Awards will air live from Nashville on June 9.
