I know Leona gets a lot of hate around here, but maybe for the other few Leona fans - she performed a few singles on Stripped. I know I know, she's extremely boring and can't dance - I'm not denying it. She sounds really good though.
I know "Bleeding Love" is an old jam, but she sounds really good at the end. If you click the link below, you can see better video/sound quality and watch "I Will Be" and "Better In Time."
