Monica lipped this performance guys! This performance was pre-recorded. It's okay to tell the truth, let's not be delusional! Monica CAN sing no doubt, but her pitch was too perfect here! And her facial expressions were a bit much! She usually doesn't get through an entire performance without having a pitch issue here or there. At 4:52, her vocals come in but her mic is not even near her mouth!

It's okay guys, Monica's lipping doesn't take away from her talent, it's still her vocals. She played it smart by having a perfect performance to promote her album.
