"We're marrying, we're totally gonna do it," Stewart told host Stern. "I wanted to be proposed to, so I think I very distinctly carved out what I wanted and she nailed it. It was really cute, she did very well. We're marrying, it's happening."

She added, "I wasn't specific at all. It's not a given that I would be the one. You know what I mean? With two girls, you never know like who's going to fulfill what weird f---ing gender role thing. We don't do that or think about it in those terms. She just grabbed that bowl and made it happen. It was f---ing so cute."

In her upcoming drama, Spencer, Stewart portrays the late Princess Diana, which she chatted about with Fallon on Wednesday night.

When asked whether it was tough to master Diana's British accent Stewart said, "Yeah, it is like so muscular. It's exhausting."

She also discussed Diana's lasting legacy.

"Her connection to people matters. That's who she was," said Stewart. "Like the reason we are telling this story still is because she reached out and touched people in a way that nobody ever really has."
