The Like A Boy songstress and Seattle Seahawks quarterback got engaged in March to Russell in March, after less than a year of dating, and exchanged vows on Wednesday.
The pair kept details of their ceremony secret and after tying the knot in Peckforton Castle in Cheshire, the newlyweds took to social media on Thursday to share the news.
They released just one photo of the day but on Saturday morning, Ciara took to Instagram to share more photos of the stunning nuptials.
More than 100 guests attended the event, while Destiny's Child singer Kelly Rowland and U.S. media personality Lala Anthony served as bridesmaids.
Serena Williams was reportedly set to be Ciara's third bridesmaid, but the sports superstar had to skip the celebrations as she prepares to compete in the semi-finals at London's Wimbledon tennis championships on Thursday.
According to E! News, the bride wore a custom Roberto Cavalli dress, which had been specially designed by the luxury label's creative director, Peter Dundas.
Other guests at the wedding included Oscar-winner Jennifer Hudson, who documented her preparations for the event on social media.
She was unable to post any snaps from the ceremony itself as all attendees were reportedly required to hand over their mobile phones to prevent any photos from leaking.
The Goodies singer and the American football star made headlines last year when they went public with their no-sex-before-marriage agreement.
After tying the knot in the English countryside on Wednesday, the newlyweds finally broke their pact and took to social media on Thursday to share the news.
In a video posted on Snapchat, Ciara asked her husband, "So, baby, you know what we're doing tonight," to which Russell responded, "From what we did last night, I'm gonna do it multiple times."
