United Kingdom, Aug. 14 -- Normani is "like a sister" to Ciara.

The 39-year-old singer is a close friend of Normani, 29, and Ciara has revealed that she actually played an important role in her engagement to sports star DK Metcalf.

Ciara - who is married to NFL star Russell Wilson, DK's former Pittsburgh Steelers teammate - said on the Not Gonna Lie podcast: "First off, I have to shout both of them out. We love them so dearly.

"Obviously, Russ and DK are like brothers, and DK is like my brother too. Our kids love them. He's Uncle DK in our house, and Normani is obviously like a sister to me.

"I think that when you see an opportunity for someone to experience love, especially in the way that you know it to be, why not?"
