The 'Goodies' singer, 30, is to wed her long-term beau, NFL player Russell.
Both stars took to social media to tell fans on Friday night (11 March).
Sharing a video of the pair announcing the news to their followers, Ciara wrote: "God Is So Good! I'm So Grateful For You @DangeRussWilson. You Are Truly Heaven Sent, and I'm Looking Forward To Spending Forever With You."
In the video, Ciara is flashing a HUGE diamond ring courtesy of her new fiancé.
She also shared a picture of the special moment he proposed, with the caption: "I Feel Complete."
Twenty-seven-year-old Russell, who plays for the Seattle Seahawks, popped the question during a romantic picnic on a private beach in the Seychelles.
Also turning to social media to share the fab news, he wrote: "She said Yes!!! Since Day 1 I knew you were the one. No Greater feeling... #TrueLove."
The pair have been dating since April last year.
In June, they made their red carpet debut together at the BET Awards.
They have also made no secret of the fact they are remaining celibate until they marry, because of their religious beliefs.
She was previously engaged to rapper Future, with whom she has a 21-month-old son, Future Zahir. Russell has been married once before to his high school sweetheart.
Congratulations to Suranne and Russell!
