Blushes for Simpson in song mix-up

Pop beauty Jessica Simpson was left red-faced at the her post-MTV Video Music Awards (VMAs) party on Sunday, when the DJ played the wrong track as she prepared to debut her new single.

The reality TV star and younger sister Ashlee hosted the star-studded bash at Miami, Florida's Delano Hotel and was hoping to play her song Fired Up to her celebrity friends.

As Jessica stood on stage and waited for the track to hit the speakers, she was dismayed to hear a different song and fled the stage embarrassed, reports the New York Daily News.

Jessica's representative says: "She wasn't going to be singing - they were just going to play a part of the single for the crowd. The wrong track was sent, so they didn't play it."
