ET spoke with Meaden at the Pacific Rim: Uprising premiere in Los Angeles on Wednesday, where he talked about his new sci-fi film as well as his relationship with Winter. The two live together, and Meaden says "nothing" has changed when it comes to their dynamic.
"Less fear, I guess. That's the only thing," he tells ET's Courtney Tezeno. "We're happier than ever. We've got three dogs, we adopted a bunny, there might be another one on the way. I guess, more animals. That's what's changed. There was two dogs to begin with, now we got another dog and a rabbit. So, in a year maybe, I don't know, a whole farm?"
Meaden, 30, even had a hard time coming up with a pet peeve when it comes to 20-year-old Winter.

"I mean, the pet peeves I kinda love," he explains. "She doesn't really know movies, which is amazing, because she's been in movies for so long, but she doesn't -- she never watched them! So, it's not really a pet peeve as much as it's something I really enjoy, because I get to show her all these old films. Probably a pet peeve of hers, because then I go into all the trivia and explain the history of the movie until she's like, 'Shut up, Levi!'"
Winter, looking stunning in a striking red dress and heels, attended the premiere to support her beau. Meaden, who said Winter visited him in Australia and China while shooting the film, explained the meaningful tattoos they have for one another. The actor showed off the ink on his finger of a jar reading "PB," which stands for peanut butter, his nickname for Winter.
"Well, I'm not sure how it came about, but she has 'Cheese' on her finger and she says, 'It's a messed-up sandwich that works,'" Meaden shares. "Peanut butter and cheese! Now, everyone thinks it doesn't, but if you try it -- depending on the cheese -- it's really good."
Pacific Rim: Uprising hits theaters on Friday.
ET spoke with Winter last November at the celebration of Modern Family's 200th episode, when she gushed about Meaden.
“I knew there was something about him from the moment I met him, honestly,” she said of the actor. “It was like I met him, and I thought to myself, ‘I don't know what it is, but there's something about him that's so interesting and maybe it will be nothing and maybe it will be something. But there's something here.’ It turns out, it was a big something.”
