The "Glee" actress told People magazine that while her fiance has been involved in the planning, she's been getting what she wants for the big day.
"At the end of the day, he knows 'happy wife, happy life!' " the 26-year-old said. "So, he's kind of like, 'Whatever you want, babe!'"
"He's so involved," she added. "We definitely bounce things off of each other [and] we're always on the same page about everything, which is probably why we're getting married."
Rivera said she's still searching for the perfect wedding gown, but so far the hunt as been "going really well."
"It's fun. It's obviously something that I've never done before, but it's so fun. It's that Cinderella, princess moment, and I went around with my friends, my mom, and it just felt amazing to try on all of those gowns," she said.
