‘Glee’ Cast Delivers Mash-Up of Adele’s ‘Rumour Has It / Someone Like You’

Next week, in the new 'Mash Off' episode of 'Glee,' our favorite characters will be pitted against each other to prove who can talk the talk and walk the walk -- and two of McKinley's sassiest will deliver a hot mashed performance of Adele's 'Rumour Has It' and 'Someone Like You.'

Santana and Mercedes will lead the all-girl show choir in the blended number, which proves that girl power still owns. Shelby Corcoran's group of stolen New Directions females take the stage dressed in all black, and from there, it's an absolute jaw-dropping scene.

Mercedes opens things up with 'Rumour Has It,' and before she really gets into the chorus, Santana waltzes in with an equally big voice and the high points of 'Someone Like You.' We hate to compare 'Glee' to superstar Adele, but, well ... Two voices are better than one, and this just may be our favorite mash-up ever.

Step back, New Directions, because this time, the stage belongs to the ladies. The 'Mash Off' episode of 'Glee' airs Nov. 15 on FOX.
