Taylor Swift is America's sweetheart for a reason: She's sweet! But she may have accidentally (or not so accidentally) dissed other artists when praising her own fans. Which artists? Oh, just two of the other biggest stars on the planet: Lady Gaga and Justin Bieber. Uh oh!

It started innocently enough.

"For me when I think about them, and I think about my fans as a group. I think about the little things. I think about the letters that I get from classrooms, and the YouTube videos of some little girl opening up her Christmas present and it's tickets to my show," she told Us Weekly. "And I think of young girls learning lessons on guitar. Sometimes I'll sit in a position where I can watch people leave the shows and I'll look at the shirts that they made and the signs and some people will cover themselves in Christmas lights so I can see them from the stage. I know that's creepy but I just like to watch."

Then it got shady, possibly indeliberately, when she added, "I just feel so proud that my fans are always nice to other fans. They don't say hateful things. They don't say they're going to set people on fire or anything. They're not sending death threats to other people."

As you know, some Beliebers and certain Little Monsters get a little too worked up when they perceive a threat to their own respective idols. Gaga made headlines recently when Kelly Osbourne claimed that some Little Monsters threatened her life, and Swift's BFF, Selena Gomez, faced a barrage of harassment when she dated Biebs. And Swift and Osbourne are pals, so chances are she was taking a dig at both.

Crafty, Swift.
