Sienna Miller's outfit is a little intense on the eyes, but she still managed to pull it off and look gorgeous when she stopped by The Daily Show with Jon Stewart on Thursday evening. Is it just us, or is the 33-year-old actress getting better with age?! She's always been a babe, but even after welcoming daughter Marlowe in 2012, it seems like she's only gotten hotter...

Sienna is making promotional rounds for American Sniper, and while she isn't nominated for her role in the biopic, the film up for a total of six nominations, including Best Picture. Sienna plays the wife of Bradley Cooper's character, Chris Kyle, and during a recent press conference she opened up about why she was so eager to get on board with the project.

"The story was so interesting to me," she told Reuters. "It is so culturally far removed from where I've grown up and the world I have lived in. It is undeniably compelling and the idea, as a new mother, of being in that position of having children and not knowing every day whether your husband would survive, and what that would be like."
