Demi Lovato - Heart Attack

Putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
Never put my love out on the line
Never said yes to the right guy
Never had trouble getting what I want
But when it comes to you, I'm never good enough
When I don't care, I can play 'em like a Ken doll
Won't wash my hair, then make 'em bounce like a basketball
But you make me wanna act like a girl
Paint my nails and wear high heels
Yes, you make me so nervous that I just can't hold your hand
