Glee cast is doing Baby!

We already knew Justin Bieber's music will turn up on an upcoming episode of "Glee" but we weren't sure which smash the McKinley High crew would be remaking — until now. 

"Glee" star Amber Riley confirmed to MTV News on Sunday (January 16) that not just one, but two Bieber jams will be made over by the cast of the hit song-and-dance show, including the Ludacris-assisted chart-topper "Baby," which was dubbed the
,most viewed music video on YouTube in 2010.

"There's gonna be two Bieber songs, and I think 'Baby' is one. I think that's correct," Riley disclosed on the Golden Globes red carpet. 

According to Riley, the Gleeks are also set to rock another Bieber-helmed dance-floor filler: "Somebody to Love." "I think ... those are the two songs," she revealed.

"Glee" co-creator Ryan Murphy also recently dished that part of Bieber's pop&B repertoire would make it into the show. In a very apt use of the pop star's teen-hysteria-inducing hits, Murphy said the Biebs' music would be the backdrop for a scene in which one of the fellas tries to win over one of the "Glee" ladies.

"Bieber comes up in episode 13 as a small plot point. Sam [Chord Overstreet] sings a J.B. song to win Quinn's [Dianna Agron] approval," Murphy said recently. 

In addition to Bieber, Lady Gaga is slated to get the "Glee" treatment once again, this time for a track that hasn't even dropped. Murphy said Mother Monster's forthcoming "Born This Way" single will serve as the inspiration for an episode about school bully Karofsky (played by Max Adler), who the show has hinted is gay.

"I love that that song is [an] anthem," Murphy said. "This show is by nature optimistic, and I think a character like Karofsky could turn to booze or pills or alcohol and kill themselves or do something dark. But I also love Max and I love that character and I sorta want that character to have a happy ending.

"So I don't really know what that's going to be," he contin

"But I do know we're going to do a whole episode that's about that song." 

What do you think of Glee doing Baby? I'm curious!
