Ciara and Russell Wilson Marry at Stunning Castle Wedding in England

Ciara and Russell Wilson are officially husband and wife.

Congratulations are in order for Russell Wilson and Ciara!

The 27-year-old Seattle Seahawks quarterback and the 30-year-old singer tied the knot at the Peckforton Castle in Cheshire, England, on Wednesday, ET can confirm. The bride wore a custom-made Roberto Cavalli gown.

"We are the Wilsons," both Ciara and Wilson Instagrammed on Wednesday.

Celeb guests included Jennifer Hudson and Kelly Rowland.

On Tuesday, ET learned that the pair had their rehearsal dinner at Stanley's Bar and Grill at the Titanic Hotel in Liverpool. Ciara -- whose full name is Ciara Princess Harris -- was spotted wearing a dazzling white halter gown as she held hands with Wilson, leading some fans to speculate that they had already exchanged vows.

Last month, the "Body Party" singer and her closest gal-pals -- including Rowland and Serena Williams -- enjoyed a weekend getaway at Wynn Las Vegas, in what appears to be her bachelorette celebration. The group took over a luxury bungalow at Encore Beach Club, and dined at the resort's Lakeside restaurant.

Ciara and Wilson made their debut as a couple in April 2015, and the pro athlete proposed to Ciara in March with an enormous 16-carat sparkler during a romantic getaway in the Seychelles. Both have been open about their decision to abstain from sex due to their religious beliefs.

But Wilson admitted to ET last July that it hasn't always been easy.

"I think we're both believers but ultimately I'll need you guys to pray for us because she's as good as it gets," Wilson candidly told ET at the 2015 Nickelodeon Kids' Choice Sports Awards. The obviously smitten Wilson described Ciara as a "stunner," and called her a "15 out of 10 in every way."

Clearly, the feeling is mutual.

"He's just an amazing guy, and he's really an awesome person ... very, very intelligent," Ciara gushed to ET about her beau at first lady Michelle Obama's speech in Detroit last May.

Wednesday marks the first marriage for both. Ciara was previously engaged to rapper Future, but the two called off the engagement in August 2014, and definitely haven't remained friendly exes. They share one child together, 2-year-old Future Zahir Wilburn.

Despite some drama regarding the "Jumpman" rapper's feelings about his son's relationship with Wilson, the pro athlete gushed about both Ciara and her little one in a sweet comment on Ciara's Instagram post in May celebrating his second birthday.

"Watching him grow over the past year and a half has been the most fulfilling and special things I've ever been around," Wilson wrote. "You both bring me pure joy and I can't wait to see him grow more and more into the loving, caring, kind-hearted man that he will be...2 years old! Wow. God is good."
