Justin Bieber strums hard on his guitar in this new shot from one of his performances at MTV on Monday afternoon (March 22) in NYC.

The 16-year-old singer’s Tuesday just got real busy — Justin was just on The View (for the second day in a row), his new album, My World 2.0, hit stores today and now he’s off to tape a segment for Late Night with David Letterman!

Earlier today (March 23), Justin was seen out to lunch with his publicist Melissa Victor. Don’t worry girls, he’s still single!

Check out his performance below and head over to MTV for more vids and pics!
