Gwen Stefani knows how to push boyfriend and country superstar Blake Shelton out of his comfort zone.

During a recent appearance on The Tonight Show Starring Jimmy Fallon, Stefani tells the late night host about taking Shelton to Disneyland for the first time and reveals that the country star is surprisingly unwilling to ride rollercoasters. "That was almost a deal breaker for me," Stefani admits. However, she did convince him to go on the Matterhorn Bobsleds and the famous It's a Small World ride, which is also Fallon's favorite Disneyland attraction.

The funnyman pulls up a great photo of the musical couple while on one of the rides — and a button on Shelton's shirt that reads "My first visit," eliciting laughs from the audience.

They also talk about the infamous video of the country singer trying sushi for the first time on Fallon's show, which went viral after it was released. Stefani says the couple went out for sushi that same night and multiple people in the restaurant were excited to see him after having just seen the video.

Stefani and Shelton are set to reunite on the coaches panel when season 12 of The Voice kicks off on Mon. (Feb. 27). The "Hollaback Girl" singer says she's "so happy" to be back on the singing show. "It is so inspiring because it's just music, the whole thing is just music," she says. "It's just full of music the whole time and it's just so inspiring, I love being there."
