"Look at my hand!" she teased on the red carpet at the Billboard Women in Music event on Friday, flashing a ring-less left hand.
"It's all about time," she told ET, responding to whether an engagement might be coming in 2016. "Everything falls in perfect timing with the way it's supposed to."
The gorgeous couple made headlines earlier this year when Wilson revealed that they had decided to abstain from sex until marriage.
"I ain't gonna lie to y'all now," Wilson said in an interview at the time. "I need y'all to pray for us. 'Cause I know y'all seen her on the screen now. If there's a 10, she's a 15."
While Ciara may have played coy when talking about her boyfriend, she couldn't help but gush about the other man in her life: son Future Zahir Wilburn.
"He's amazing! He is walking and talking. He is 18 months going on 3 years old," she joked. "He is so tall, but he's moving along so well. I'm so proud. He literally is in the parrot stage. ... It's the cutest thing in the world!"
Looking stunning in Versace, Ciara stepped out in New York City to present pal Missy Elliott with Billboard's Innovator Award.
"She is the true definition of being an innovator and she's my sister, as well," Ciara said. "Every time she does something, I get so excited. What people may not know is, she's truly a perfectionist and she gets really shy, very protective, of her work. I watched her take so much time to get ready for this moment, for this new video and all the new things she's doing right now, and it's just like, I have so much respect for her."
Elliott made a triumphant return to the spotlight at the Super Bowl this year (coincidentally, where Wilson and the Seattle Seahawks faced off against Tom Brady and the New England Patriots). In honor of the show-stopping performance, ET took a look back at a 2002 flashback with the iconic artist.
