Mike Fisher wants seven kids with Carrie Underwood

Washington, May 20 (ANI): Carrie Underwood and Mike Fisher can't mutually decide over the number of children they hope to have.

In a joint interview on Oprah's Next Chapter, Underwood, 29, said that while Fisher, 31, grew up with "three siblings, I think two is a good number to have," the country crooner tells host Oprah Winfrey, 58. "We'll see. We'll cross that bridge. I don't want too many," Us magazine reported.

Although Fisher insists he'd be happy with "two or three" children, Underwood joked that usually, "He's like, 'I want seven!'"

While Underwood and Fisher don't have immediate plans to start a family, Underwood predicts her husband of nearly two years "is going to be the best dad ever, and that makes the whole parent situation seem much better."

The "Blown Away" singer also admits that she still "can't believe" she's off the market.

"Sometimes I still have those moments where I can't believe I'm married. I spent 27 years not being married and I kind of got used to it," Underwood said.

"But now, the more I do it, the more I'm able to think more of 'we.'

"For the first year of our marriage, I still would give people gifts and write: 'Love, Carrie. And I'm like, OK, now I'm 'Carrie and Mike'-there's two of us now. But I'm getting better all the time," she added. (ANI)
