'Glee' Season 6 Spoilers- Naya Rivera, Heather Morris & Dianna Agron Back In Cheerio Uniforms On Set Of Fox Musical Comedy

School is back in session for three of our favorite Glee cheerios. The three best friends that anyone could have Santana Lopez (Naya Rivera), Quinn Fabray (Dianna Agron), and Brittany S. Pierce (Heather Morris) are all back and looking redder than ever in their brand new McKinley High cheerleading uniforms.

In new pictures that E! News posted, the girls are looking as close as ever, as they hang out in their uniforms on the McKinkley football field.

However, we are just a little bit confused as to what brought the girls back to their high school and why they would be wearing these outfits.

As we know, the girls have all graduated and move on from Lima, Ohio. Quinn went off to Yale, while Brittany scored acceptance to MIT, and Santana made her way to New York City, so what exactly brought them back?

It can't be a flashback scene since as creator Ryan Murphy said that the sixth and finale season would jump ahead in time by six months, and we are pretty sure that it's not a time warp. Whatever the reason may be for the sudden reappearance of our three favorite cheerleaders, we couldn't be happier.

Murphy previously explained that anyone that wanted to come back to the series would be able to do so during the final season.

"Anybody who wants to be a part of the show, we welcome them," Ryan explained to E!. "My feeling about the last season of Glee is very clear, and that is that we will be reaching out to all the regulars on the show, that original group of Glee club members, and the teachers, and anybody who wants to come back can come back."

The sixth and final season of Glee will air in 2015.
