After being called out for her barely-there stage costumes and girl-on-girl kiss, Miley Cyrus dismissed the critics who say she's grown up too fast.

"I've gone through awesome things and I've gotten to perform and do what I love," Cyrus, 17, told David Letterman Thursday night. "I don't think I've missed out on anything, but it's hard with the comments and growing up."

What kind of comments is she referring to?

"You can YouTube me, because half the comments are like, 'She sounds like crap!'" she complained. "I'm like, 'At least I'm singing live, so take that!'"

It isn't the first time the teen queen has been teased on the web. In Oct. 2009, the singer deleted her Twitter account at the request of her boyfriend of one year, Liam Hemsworth.

"Someone was making fun of me in some skit the other day and I was like, 'I lost my lucky bracelet.' Two minutes later: 'Woohoo! I found my lucky bracelet,'" Cyrus recalled. "And it's like, oh my God, can I think of something a little more interesting?"

Cyrus also added that posting frequent Twitter updates made it easier for paparazzi to trail her.

"You can't complain, Oh, I don't have a private life and I'm so upset paparazzi are gonna follow me if you're gonna tell them where you're going," she said. "Paparazzi are gonna find you when you say I'm at McDonald's."
