RED-BAND TRAILER: Leslie Mann Talks About Megan Fox's Boobs in 'This Is 40'

I don't know if anyone was really clamoring for a "kind-of" sequel to Knocked Up, but Judd Apatow's latest movie is speeding towards theaters anyway. This Is 40 focuses on Pete and Debbie, the Knocked Up characters played by Paul Rudd and Leslie Mann, as they struggle with their marriage and growing older. Kids, parents, jobs and Megan Fox apparently weigh heavily on relationships at this age.

A red-band trailer hit the Internet on Monday, but don't get too excited — it's only red band since there's swearing in it. You can check it out after the jump.

This Is 40 also stars Jason Segel, Melissa McCarthy, Albert Brooks, John Lithgow and Chris O'Dowd. It hits theaters on Dec. 21, 2012.
