Big Time Rush are Big Time Penguins -- FIRST LOOK!

Big Time Rush chill out inside the Nickelodeon Animation Studios as they take a break from recording for The Penguins of Madagascar on Tuesday afternoon in Burbank, Calif.

The guys — Kendall Schmidt, Logan Henderson, James Maslow and Carlos Pena — will be voicing four BEAVERS in an upcoming episode.

What a cool treat for birthday guy Logan — he turned 22 today!

James tweeted about the session, “So I just did a voice over for Penguins of Madagascar…one of the coolest things I have done in a long time!”
