Last night’s Glee Season 3, Episode 10, “Yes/No” featured a gorgeous and stirring rendition of the Usher and David Guetta hit “Without You” — sung by none other than Rachel Berry (Lea Michele).

Rachel sang the tune to show her struggling boyfriend, Finn (Cory Monteith), how much she cared about him. It certainly worked! (Though, we’re not sure a marriage proposal was exactly how Rachel expected Finn to respond.)

In any case, the memorable Glee song is already a major hit on the music charts, bounding up to #1 on iTunes on the day after the show.

Just before noon on January 18, Lea tweeted, “OH MY GOD! "With Out You" is #1!!!! That's so amazing!!! #Powerofthegleeks”

Cory was quick to chime in, tweeting, “congrats to @msleamichele ! #1!!!! #WithoutYou”

Co-star Mark Salling (Puck) wrote, “Big ups to my girl @msleamichele for her number 1 track on iTunes.” A number of Lea’s other castmates also tweeted their support.

Glee’s executive music producer Adam Anders tweeted, “Congrats @msleamichele!! We did it! #1!”

Lea promptly responded, “@AdamAnders @alxanders thank you for your amazing arrangement!!”

So many good song’s in Glee last night, but we think the praise for “Without You” is definitely well-deserved. What did you think was the best performance of the evening?
