The Secret Behind Nick Jonas’ Smile

Arguably the hottest brother from the JoBros, there's no question that Nick Jonas' smile makes girls weak in the knees.

But why? What's the secret behind it? What makes his smile so enchanting?

It could be the fact that he has THREE front teeth! Yup, check out those chompers.

It's a little hard for me to look at Nick the same after learning about his strange smile, but lets be serious, it doesn't make me think any less of the Hollywood hunk.

Keep flashing those pearly whites, Nick. You're still Burnin' Up.
