Oops, they did it again.
The kids of "Glee" are tackling Britney Spears for the second time with this Thursday's episode, "Britney 2.0."
And we've already got a sneak peek at one of the songs -- with a brand new clip showing Brittany S. Pierce (Heather Morris) and the Cheerios performing "Hold It Against Me."
The episode will also include performances of "Womanizer," "Gimme More," "3," a mash-up of "Boys" and Justin Bieber's "Boyfriend," "Everytime," "Oops! I Did It Again" and an amazing mash-up of "U Drive Me Crazy" and Aerosmith's "Crazy."
No word yet on if the real Britney will appear in the episode, which will air after the pop star judges more wannabes on the fourth episode of "The X Factor."
Brit memorably made a number of small cameos on the first tribute episode last season. Fingers crossed she pops up again!
