"I'm literally turning 23 this week," Lovato, whose birthday is tomorrow, said last night at Samsung's Galaxy S6 edge+ and Galaxy Note5 launch event in West Hollywood. "There's no rush. We've been together so long [that] there's no rush."
However, that hasn't stopped the "Cool for the Summer" singer from planning her big day.
"Every girl does that," Lovato said. "I was planning my wedding when I was like 10!"
She recently revealed that she wants Ed Sheeran to perform at her nuptials.
She's also relying on Pinterest for ideas and inspiration. "All of a sudden you have your whole wedding planned out and you don't even have a boyfriend," Lovato said of the image-collecting app.
Valderrama teased in February that he and Lovato will likely get married. He just doesn't know when.
"It's something that I definitely look forward to in the future," the From Dusk Till Dawn star told me. "We'll see."
Lovato also revealed that she and Valderrama do take time-outs from their mobile phones. "We will at dinner not touch our phones because if one of us is talking and then you get on your phone, it's rude," she said.
