David Duchovny and Gillian Anderson are back on the big screen as FBI agents Mulder and Scully in the new movie 'The X-Files: I Want To Believe,' in theaters everywhere Friday, and Gillian gave us the latest on her growing baby bump: It's a boy! ET was on the scene with the movie couple at their big Hollywood premiere, where the expecting mother shared her thoughts on co-star Duchovny playing the role of babysitter. Gillian's response? "That's really funny, I think he would be nervous about it, it would force him into being really protective."

Picking up six years after the end of the original TV series, the new movie is a stand-alone story that takes the complicated relationship between Fox Mulder and Dana Scully in unexpected directions. Of course, the unexplained and the paranormal is still very normal and sometimes lethal in the 'X-Files' universe.

Watch ET for more with Gillian and David at the premiere!
