Miley Cyrus Proves She Never Lip-Syncs (VIDEO)

Teen pop sensation Miley Cyrus made a visit to the Late Show with David Letterman on Thursday night to help bring host David Letterman up-to-date on things like Twitter and the internet.

Dave and Miley looked like they were having a lot of fun together, with Miley declaring that they were both “17-year-old girls” who were lucky enough to be able to handle the pressures of fame.

Dave tried to get in a few good-natured jabs at Miley, asking her if she knew who he was since he thinks of himself as being so old and out-of-touch. Miley expertly joked it off by announcing that she knew who he was and then mouthing “I think” towards the audience. Of course Miley knows who you are, Dave!

Miley also talked about how she “hates Twitter” and that when she had a Twitter account she would write about unimportant things like losing her “lucky bracelet.” Miley deleted her Twitter account reportedly because her current beau Liam Hemsworth didn’t like the micro-blogging site.

The “Can’t Be Tamed” singer also explained that she never lip-syncs during concerts. She said you can tell she doesn’t lip-sync because people leave nasty comments about her singing skills on YouTube videos of her live performances.
