The couple tied the knot on Wednesday at the Peckforton Castle (we know, a castle is so fitting) in Cheshire, England, and a source tells E! News exclusively it was a dream come true and more.
The insider revealed that Ciara was treated like a queen by all of her bridesmaids (who wore black for the affair). They stayed by her side and helped her get ready in her suite from morning until the ceremony finally kicked off around 6 p.m.
The source tells us it was a very traditional and "heartfelt" ceremony, filled with flowers and clean, classic decor. A pastor said some "enlightening" words, incorporating their love of faith and God into the nuptials. The happy couple also took a moment to share words from their heart with one another, while a few personal speeches were mixed in throughout.
Our insider said Russell could barely keep his composure as Ciara—who wore a custom Roberto Cavalli dress, designed by the label's creative director, Peter Dundas—walked down the aisle toward him, looking like a "big, teary-eyed teddy bear." She, too, was shaking as she tried to hold back her tears.
"Both of them were extremely nervous," the source said.
Ciara's son, Future, stood by the pair's side throughout the ceremony, and the insider said he "looked so cute and behaved very well" the whole time.
The ceremony ended when they said "I do" and shared a "very passionate" kiss, holding onto each other tightly. "It was not a quick kiss. They were locked," our source explained. "Everyone got so excited. [There] was not a dry eye in the room."
Meanwhile, since Ciara and Russell married in England, they will still need be legally married in the United States. E! News has learned that they've already applied for their marriage license in King County, Wash., but they will need to return there in order to be legally wed.
The pair has already shared their first photo from the wedding on their respective social media accounts, both captioning the sweet pic, "We are The Wilsons!"
Congrats again and again to the happy couple!
