You'll Never Guess What Anna Faris and Chris Pratt's Son Is Dressing Up as For Halloween

Anna Faris talked about Halloween on Jimmy Kimmel Live on Thursday, but she's not the one who's dressing up. Instead, she dished on her son Jack's very appropriate costume! "We let him pick his costume this year," Anna explains, "and he's decided to become . . . he's a dinosaur, a T. rex. Which . . . it's adorable, but it also adds sort of a layer of . . . a little bit of weirdness, because of course, my husband is Chris Pratt." Anna's obviously referring to Chris's turn in Jurassic World, and she's understandably worried the costume will send the wrong message. Watch the funny clip above, then look at her cute family pics with Chris and Jack.
