'Glee' Season 4 pays tribute to Britney Spears (again) in new pictures

"Glee" has already paid tribute to the current queen of pop, Britney Spears, but once wasn't enough for the Lima, Ohio gang. The second episode of Season 4 will once again honor Spears, but with a new group of hit songs.

FOX has released new photos from the episode, titled "Britney 2.0," and they're quite telling (even though we still don't know that much about the new season). For one, it's obvious Rachel's chemistry with her new classmate Brody will sizzle in the ep, if the steamy pics of her dancing with the upperclassman are to be believed.

Second, "The Glee Project" Season 1 runner-up Alex Newell is back in a big way, as his character, Unique, transfers to McKinley High and evidently has a ginormous dance number in episode 2.

Third, newbie Jacob Artist looks good in a leather jacket. Those rebellious Puckerman genes are alive and well in Puck's little bro.

The Spears tribute airs Wednesday, Sept. 20 at 9 p.m. on FOX.
