Joe Jonas‘ glasses are so he can see, not for vanity.
From Stephanie: I went to watch the Kevin Jonas special on Minute To Win It in the CBS Studios in Studio City, CA. I waited for two hours with my friend and got to sit in the front row. I think I was the only one to have a picture taken with him cause security was called afterwards. Nick is the sweetest person ever.
And Kevin J IS COMPLETE BEAST AT THE GAMES. Everybody must watch that episode. He won 250,000$ for his charity! :] He made MTWI history. He is suuuper handsome, and was really sweet to the audience and made random, cute comments to his wifey throughout the show. There is one time when he tapped his heart twice at Nick, and Nick did the same back. It was cute. :]
