Congratulations are in order for Kristen Stewart. The "Twilight" actress revealed during her appearance on SiriusXM's "The Howard Stern Show" Tuesday that she is engaged to her longtime girlfriend and screenwriter, Dylan Meyer. "We're marrying, we're totally gonna do it," Stewart told Howard Stern in the interview. "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." She also discussed her wedding plans, saying she wants to keep it "chill." "I want to stay home. I want to be in L.A. so everyone can come and … I want it to be pretty chill. I don't want anyone walking anyone down any aisles like we're just gonna stand, do vows," she said, and of course "party after." She also said she doesn't plan on wearing a traditional wedding dress, but rather "the best pair of Levi's ever, an old T-shirt that has a tuxedo printed on it." Photo by Eamonn M.
