They’ve been in a happy relationship for just over a year now, but Gwen Stefani has revealed that a recent family trip to Disneyland almost made her reconsider her romance with Blake Shelton – he wouldn’t go on the rollercoasters!

The 47 year old pop star was a guest on ‘The Tonight Show’ on Wednesday (February 15th), and she told host Jimmy Fallon that his reluctance to get on the big rides had her thinking twice for a bit.

“I know that for me, I just go anywhere, and I know I'm gonna get hounded for pictures or whatever… he's in the woods most of the time but, yeah, we went. It was crazy. It was, like, a billion people there,” Stefani said. “He [wouldn't] do the rollercoasters! That was literally, like, that was almost a deal breaker for me. I was like, ‘I don’t know’.”

However, Stefani went on to admit that her 40 year old country singer beau may have a good reason for not wanting to get on them. “He doesn’t fit in anything… We did go on the Matterhorn, he did. But he barely fit inside the little thing. His knees were up like this!”

The former No Doubt singer began dating Shelton back in late 2015, shortly after she split from her husband of almost ten years, Gavin Rossdale. They’ve since worked together on ‘The Voice’, and have duetted together and performed onstage.

Late last year, Stefani went on a family outing to Disneyland Park, Anaheim, with her three children – Kingston, 10, Zuma, 8, and Apollo, 2 – and brought Shelton along with her.

Although they enjoyed their day, Stefani told Fallon that he doesn’t really like “going out” because he gets recognised too often.

“We walked into [a] sushi restaurant and literally the entire restaurant stood up and was like, 'Blake!' It was like the whole world had just watched it, and we walked in the room. I felt so bad. He really is a country boy… I think he’s quite miserable when he’s not in the woods or, like, somewhere in camo. He really likes to be camouflaged.”
