Jessica Simpson stuns guests with impromptu piano act

  Jessica Simpson

Jessica Simpson's impromptu performance at Shreveport, Louisiana's Olive Street Bistro, has landed her a regular spot at the restaurant.

The busty blonde, who has been filming new film Major Movie Star nearby, wowed diners by taking the piano when restaurant dishwasher Marshall Collier sat down to play for diners.

And restaurant manager Fernando Maldonado was ecstatic when Simpson belted out classics like Midnight Train To Georgia and Desperado for his guests.

Too impressed by her performance, Maldonado immediately offered Simpson a regular place on his stage.

"It was so fantastic. Jessica is welcome back here any time," Contactmusic quoted Maldonado, as saying.

Simpson booked a table at the Shreveport diner to celebrate pal and hair stylist Ken Paves' birthday.
