R&B star Kelly Rowland has confirmed her engagement to boyfriend Tim Witherspoon.

The former Destiny's Child singer sparked speculation she was set to marry her longtime manager last month, when she showed off a diamond ring on her wedding finger during an online video.

And in an interview with Queen Latifah on her talk show, due to air on Wednesday, Rowland exclaimed, "He put a ring on it!", before holding up her hand for the audience to see.

The 32-year-old admitted that she had worked hard to keep her romance out of the spotlight from the beginning, adding, "It's been a while. We've kept it very, very low -- for years, to be completely honest."

Rowland also revealed the proposal had been less than traditional: "He asked me first on Skype and I was like, 'We're so far away from each other.' But it was so late, I remember we were both just kinda like, honestly, just staring at each other. And he asked me, and it was just that simple to say yes. I was like, 'I got my best friend to ride through life with.' He really is my best friend."

It's the second engagement for Rowland; she accepted football player Roy Williams' proposal in 2004 before calling off their plans to wed the following year.
