As if you didn't see this sequel coming. Steve Martin, Bonnie Hunt, Piper Perabo, Tom Welling, and Hilary Duff will reunite this Christmas for "Cheaper By the Dozen 2," as directed by Adam Shankman. Oh, and you can see the trailer right here.

"The Baker family goes on vacation, which turns into a head-to-head competition with a rival neighborhood family of eight children." There's your plot. And let's not forget that Eugene Levy is now on board, as the dad who's most likely a broadly obnoxious comedy villain.

"Cheaper By the Dozen 2" hits theaters on December 21st, while the also kid-laden remake of "Yours, Mine and Ours" debuts in multiplexes on November 23rd. Whichever flick you pick, I suggest packing a few aspirins.
