Lady Gaga gave the Capital Children's Choir her stamp of approval after the young group posted a haunting rendition of the pop star's hit 'Judas.'

"This is so flawless and otherworldly," the singer tweeted on Thursday with a link to a video of the cover. "What a beautifully haunting arrangement of my song. You girls are so talented."

The clip shows the older girls from the London-based singing club using their voices in rounds and layered harmonies to put a beautiful spin on the club-ready track. The song was arranged by choir founder Rachel Santesso, who, according to the video's description, received a special request from Perez Hilton to cover the tune.

The Capital Children's Choir is no stranger to producing pop covers. The group, which boasts over 100 members, has created renditions of songs by Lily Allen, Elton John, Bjork, Guns N' Roses and more. In fact, the choir was even invited to sing alongside the Spice Girls on 18 dates during their 2008 reunion tour.

With such an impressive resume, it wouldn't be surprising if Gaga came a-knockin'. We bet the girls would do a bang-up job backing the singer on 'Bad Romance' and 'Americano.' Just sayin'.
