Asked about the widespread speculation – on the Web and in tabloids – that's she's had a nose job, the 21-year-old singer giggled and told the Associated Press: "Everybody's already saying it, so I just don't talk about it. I'm like, okay, whatever. It doesn't bother me."
Yet when the news service tried to put her nose to the grindstone and get her to confirm or deny the rumor, Simpson did neither – she just giggled more.
"Maybe," she said. "Who knows!"
Still, a source tells PEOPLE that part of her new long-and-blonde look is, indeed, a nipped-and-tucked nose.
"He's the yin to my yang; people call him my 'Little Buddha,'" she says. "When he comes around, everything changes. Braxton has taught me a lot."
Simpson, whose latest album is I Am Me, kicked off her summer tour last weekend in West Palm Beach, Fla.
