Heather Morris, who plays hilariously ditzy cheerleader [article id="1648829"]Brittany on "Glee,"[/article] got to channel her sort-of namesake on Tuesday night's [article id="1648932"]"Britney/Brittany" episode[/article]. And the professional-dancer-turned-actress didn't disappoint as she re-enacted Spears' videos for "Toxic," "Slave 4 U" and [article id="1646145"]"Me Against the Music."[/article] She tackled all of them with her spectacular dance skills and a pretty killer singing voice.

The anesthesia-induced dream sequences followed one of Brittany's stellar reveals: "My name is also Britney Spears. Brittany S. Pierce. I've lived my entire life in Britney Spears' shadow." Well, on Tuesday night she stepped out of her shadow.

Of all the video reinterpretations in the episode, the Madonna/Britney team-up, which saw Santana playing Madge and Brittany playing you guessed it, paid homage to the original 2003 video, directed by Paul Hunter. Aside from a few artistic tweaks in the "Glee" version's choreography, Morris and company do the original justice.

"The 'Me Against the Music' montage, it's literally copied exactly from the video, the shots and looks, but the choreography is made so much more for a dancer -- none of it is from the video," Morris told New York magazine about the "Glee" version. "You just have to wait to see it. It's insane."

Hunter spoke to MTV News last year about his original concept for [article id="1626705"]Britney's "Music" video[/article]. "I try to play opposites, when you have Britney in dark and Madonna in white," he said. "And then we see them kind of dance around the bed .. and you think they're gonna get on top of each other and do something crazy."
