Christina Applegate appeared on David Letterman last night where she is promoting her movie Going The Distance where she plays Drew Barrymore’s sister.

She talked to David about her pregnancy hormones and how before she used to always want people to like her and now she has ‘no filter’:

“This security guard started yelling at us for parking there, and I went, ‘Shhh, shhh! It is too hot out to be a douchebag, OK?’” Applegate said. “Whoam I right now? … That is a horrible thing to say to somebody!”

It’s too cute.  I love this woman!

Will you be going to see Going The Distance?
