Quite a night on NBC's The Voice. First Adam Levine showed up with his hair peroxide white. He said he felt like a cyborg from the future. Blake Shelton expressed shock. "That's Adam?" he said. "I thought Meg Ryan had joined the panel."

Speaking of joining the panel, next season's superstar additions made an appearance – Gwen Stefani and Pharrell. They even collaborated on "Hollaback Girl".

Among the eight remaining contestants, the competition was fierce and the bar was exceedingly high. For the first time tonight, three will be eliminated.

Delco country singer Audra McDonald made a strong bid for the semis with this turbo-charged performance of Rebecca Lynn Howard's power ballad, "Forgive".

Afterwards Shakira and Blake both called the 23-year-old from Glenolden "unstoppable". We'll find out tonight if they're correct.
