Amanda Peet was back on the red carpet yesterday at the premiere of the X Files movie, looking as beautiful as always and without a trace of extra weight, after having given birth just a year ago. Apparently motherhood looks good on some, and Amanda is among that group of lucky women.

Dressed in a glittery black frock, Peet showed her perfect body for the first time, following a whole year and a half of being MIA. After a very busy period as a brand new parent, Amanda went back to work playing Dakota Whitney, the sexy Special Agent who will dazzle you with her sleek moves and her wittiness. Even if you can't stand Gillian Anderson, just watching Amanda Peet in tight pants will make this movie worth watching.
