Hit me, Lisa, one more time! 

Lisa Rinna channeled her inner school girl on ABC's new reality competition show, "Sing Your Face Off," singing Britney Spears' 1999 smash hit "… Baby One More Time."

Rocking Brit's signature pigtails, plaid skirt and belly-bearing collared shirt, the 50-year-old actress went all in, mirroring the pop star's original choreography while she sang.

Unfortunately for the "Celebrity Apprentice" star, the judges were less than impressed by her performance, as Debbie Gibson, Darrell Hammond, and guest judge RuPaul gave her the lowest combined score. 

"It is a nonstop process for only five days, which is not a long time," Rinna told People on Thursday. "I knew I just had to throw myself into it and cram like I was cramming for finals, really. I just went for it and I knew I would have to go hard or go home. This is the kind of thing where you can't just dip your toe into the water. You have to dive in or you will crash and burn."

"I had a blast doing it," she added. "Britney is so specific and she's an amazing performer, and when you really break someone down like Britney, she's technical and does certain things with her voice that are very difficult. She's a great dancer and it was really challenging to become her."
