Reese Witherspoon and Seth Rogen: Monsters in LA

Taking to the red carpet for her upcoming movie, Reese Witherspoon was all smiles at the Los Angeles premiere of "Monsters vs Aliens" on Sunday (March 22).

The "Legally Blonde" babe joined up with co-star Seth Rogen, as the pair greeted fans and posed for pictures at the Gibson Amphitheatre on the Universal City grounds.

Due to hit theaters in the States next Friday (March 27), Reese's animated flick tells the story of a young girl who turns her into a giant monster when a meteorite from outer space hits her, as she's then taken to a secret government compound where she meets a ragtag group of monsters also rounded up over the years."

Telling press how much her two children, Ava and Deacon, love her latest theatrical work, Miss Witherspoon said, “I have all the action figures. As soon as I saw my own action figure, I ripped her out of the box and started playing with her. My kids love it, every morning we play with them. I have to pretend to be a giant robot.”
