"We're marrying, we're totally gonna do it," Stewart told Stern on his SiriusXM show. "I wanted to be proposed to, so I think I very distinctly carved out what I wanted and she nailed it. We're marrying, it's happening."
Aside from her engagement, it's about to be an amazing next few months for Stewart! She is currently starring in Pablo Larrain's upcoming biopic Spencer(which is already garnering her huge Oscar buzz) as the legendary Princess Diana princess as she decides to leave her life with the royals over a holiday weekend.
After that, she's starring with Viggo Mortensen and Lea Seydoux in David Cronenberg's sci-fi film Crimes of the Future, which takes place in a near-future where "humankind is learning to adapt to its synthetic surroundings" and evolving into transhumanism.
