Britney Spears has always had her share of doubters, but in an upcoming episode that plays homage to the singer, the students of William McKinley High will have her back as they fight for the pop princess, according to castmember Heather Morris.

In an interview with Australian magazine TV Week, the actress dished about the plotline surrounding next week's "Britney/Brittany" episode and what it was like working with the pop icon.

"Through a special substance, I go under and have a couple of dream sequences — not only myself, but with Santana [Naya Rivera]," Morris explained. "A lot of it has to do with Will [Matthew Morrison] not allowing us to perform Britney Spears songs, because he doesn't agree with what kind of entertainer she is, so it's our fight to do Britney. But it's not just us doing Britney in show choir; there are other sequences — it's our homage to her."

In the episode, which airs next Tuesday, viewers might catch a rendition of Spears' 2003 hit collabo with Madonna "Me Against the Music." Last month, the singer tweeted on-set photos of her and Morris re-enacting a scene from the girl-on-girl clip. Aside from the Madonna collaboration, " ... Baby One More Time" and "Toxic" are also reported to be part of the episode.

Morris told TV Week she wasn't nervous to work with the pop star since it wasn't her first encounter with Spears. "It wasn't really nerve-racking, because I've met her before and I wasn't really overwhelmed by who she is," she admitted. "But the idea of what she has given us for the show and, for me, getting to dance with her and play with her on set, I was just staring at her at one point and thinking, 'This is just so frickin' awesome.' "

While show creator Ryan Murphy has already revealed his admiration for the singer, Morris' idolization might be a bit more personal. "She was my idol from, like, age 12 to 16," she told the magazine. "I sang to her [songs] in my living room and danced to her — I learned all her moves. And I had my talent shows and I lip-synched to her. I just kept flashing back to growing up and being obsessed with her."

The 23-year-old actress might not have been fazed by Spears' presence, but that wasn't the case for everyone on set. "It was literally like the president had come," Murphy previously said. "We all had to wear wristbands. I couldn't get into my own sets at one point, which I thought was hilarious."

Mr. Schuester isn't the only character worried that Spears' music will wreak havoc on the halls of McKinley High. "Sue Sylvester is of the opinion that Britney Spears is basically the anti-Christ," Jane Lynch told TV Week of her character. "How does she put it? 'A pop-culture provocateur and responsible for every out-of-control impulse ever created.' So she fears that if Britney Spears' music is played, it will create a sex riot — and it does."
