EXCLUSIVE: Russell Wilson Dishes on Keeping His Wedding to Ciara a Secret And Having Kids

The superstar quarterback is a new husband, but he admitted not much has changed.

Russell Wilson is a new husband after tying the knot with Ciara last week, but he admitted to ET that not much has changed.

"No, not at all," the Seattle Seahawks quarterback said when asked if marriage felt any different. "We're so close. She's my best friend, and we're madly in love with each other obviously. We're the Wilsons now, so it's pretty cool."

The ceremony was shrouded in mystery. Almost no details were leaked ahead of time, but Wilson told ET it wasn't difficult to keep the nuptials secret.

"We had about 100-plus people there at the wedding -- really close friends and family," he explained. "They understand it's about love and keeping each other close and keeping it real tight knit, so that was easy to do for the most part. Everybody kind of kept their mouth shut."

The hard part, according to Wilson, was the trip to England, but once they got there, they had a great time.

The couple exchanged vows at the Peckforton Castle in Cheshire, England, on July 6. The bride wore a custom-made Roberto Cavalli gown, and notable guests included Jennifer Hudson and Kelly Rowland.

Wilson wasn't the only sports figure to get hitched this month. Derek Jeter wed model Hannah Davis over the weekend. "When you find an awesome person -- an awesome lady to be your wife -- it's a good thing,” the 27-year-old NFL pro said of his fellow athlete’s big day.

"It's a good thing," Wilson said about Jeter's nuptials. "When you find an awesome person -- an awesome lady to be your wife -- it's a good thing."

ET caught up with Wilson during preparations for the Kids' Choice Sports 2016. He is hosting for the second consecutive year, and the event should be fun for Ciara's 2-year-old son, Future Zahir, whom she shares with her ex, rapper Future -- and the only child the newlyweds are worried about at the moment.

"We'll take one at a time. Ultimately, it's just about spending quality time with each other," Wilson said. “We're excited. She's excited to be here for this week -- and it's going to be an awesome week -- and we're excited to just have a lot of fun with the kids here at Kids' Choice Sports. It's going to be a great time."

Kids' Choice Sports airs July 17 on Nickelodeon.
