Jessica Simpson [1] brought the LOLs with her Halloween [2] costume this year. The singer and footwear mogul teamed up with her husband, Eric Johnson [3], to re-create a movie poster from the 1988 buddy comedy Twins. Jessica was unrecognizable in a bald cap and suit as she struck the classic pose as Danny DeVito, while Eric sported a matching getup while channeling Arnold Schwarzenegger [4]; in the film, the actors play fraternal twins who are separated at birth.

Eric and Jessica, who is pregnant with the couple's third child [5], are certainly not strangers to the funny costume game. Last year, they dressed as Waylon Jennings and Willie Nelson [6], and back in 2011, Jessica announced her first pregnancy with a clever "mummy" costume [7].
