Aca-scuse-me? Yup, you heard it right. The Barden Bellas are back, pitches! The girls of "Pitch Perfect" have reunited three years since the release of "Pitch Perfect 3" in an acapella rendition of Beyoncé's 2011 hit "Love on Top".

Britanny Snow shared the performance to her Instagram, where she informed fans that they are reunited "making music with our mouths for two very important reasons: Beyoncé and a great cause". The performance has all the big-name Bellas, such as Hailee Steinfeld, Anna Kendric, Anna Camp, Rebel Wilson, and more.

 The description of the video also explains why the Bellas decided to reunite, saying "There is nothing perfect about the world we are living in. Families around the globe are suffering from the impact of the #COVID19 pandemic, especially those in Lebanon who are facing crisis after crisis. But we can all pitch in and help."

They go on to say that the proceeds raised from downloads and streams of their acapella rendition of "Love on Top" will go to UNICEF, to help children and Lebanon and around the world during these difficult and trying times.

Their cover also features a fun introduction from Pitch Perfect announcers John Smith, played by John Michael Higgins, and Gail Abernathy-McKadden, played by Elizabeth Banks. John starts by saying that Barden Bellas are back together again, and how not even a quarantine cannot prevent them from "harassing us with another musical performance."

Gail goes on to say that John has a "cold, dead heart" and proceeds to introduce the Bellas and their performance. "The Bellas are back with a reimagined classic to support UNICEF, who are on the ground of 192 countries, doing whatever it takes to protect kids from the coronavirus pandemic." She encourages people to download the song, as the proceeds will go to UNICEF.

A SHORT SYNOPSIS OF PITCH PERFECT

Pitch Perfect is an American film trilogy directed by Jason Moore and written by Kay Cannon. The plot follows Barden University's all-female acapella group, the Barden Bellas, as they compete for their way to get to Nationals. It follows Beca Mitchell (played by Anna Kendrick), a college freshman, who initially wants to drop out of school to become a music producer in Los Angeles. After making a deal with her dad to join one extracurricular activity (with the premise that if she likes it, she stay and if she hates it, he will support her dream of becoming a music producer), she joins the Barden Bellas.

She is initially withdrawn and resentful of Barden Bellas president Aubrey Posen (played by Anna Camp) and her uptight and traditional ways of ruling the Bellas. At one point, she even gets kicked out of the Bellas for suddenly adding a song to their setlist at the ICCA Semi-Finals, which was not agreed upon by Aubrey.

By the end, she asks the Bellas for a second chance and rejoins the group, with Aubrey giving half her leadership to Beca. They end up winning the national championship and by the second movie, Becca is made president of the Baren Bellas.
