Demi Lovato 'Laughs Off Butt Chin Insults'

Demi Lovato has laughed off cruel remarks about her appearance, and has decided that rather than be upset by people's comments, she would see the funny side.

Comments like "fat knees" and "butt chin" are obviously meant to hurt the pretty teen star, but instead Demi chooses to make jokes about peoples lame attempts at insults.

"It actually really used to bother me when people would make ugly comments about the way I look... But then someone called my knees fat and I couldn't help but laugh out loud... Hahaha thanks for the laughs haters!" She writes on Twitter.

"I think I'm gonna go do some knee exercises now... Nothing else. Just working out my knee 'flab'."

Lovato adds: "Oh! And about my 'butt chin' (or as I like to call it my booty chin) it's called a cleft chin! And lots of people have them! :)"

"Just look at this fine piece of bootychin…. Ladies and gents, Ben Affleck, stud muffin/actor. BAM! :)3"

"Like seriously... if they made jeans for your face... my chin would look fiiiiine!"
