Kelly Rowland married her manager and fiancé Tim Witherspoon Friday, Billboard has confirmed. The nuptials took place in Costa Rica with around 30 guests. Congrats to the new happy couple!

The former "Destiny's Child" songstress announced her engagement in December on Queen Latifah's show.

"He put a ring on it," she confirmed. "It's been a while. We've kept it very, very low -- for years, to be completely honest."

"The X Factor" host was in Bulgaria when Witherspoon proposed via Skype.

"He asked me first on Skype and I was like, 'We're so far away from each other,"' Rowland recalled of the moment.

"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."

She appeared at the American Ballet Theatre Spring Gala in New York Monday, keeping her hands in her pockets. Neither party has officially confirmed the news yet.

A source tells Us Weekly the wedding was "quick and simple." Beyoncé and sister Solange Knowles were present for the event, jetting from the Met Gala after the Jay Z incident.

Beyoncé uploaded a picture to Instagram that day in what appeared to be a bridesmaid dress, captioned "Good Morning."

Other guests included fellow band member Michelle Williams and Beyonce's mother, Tina Knowles.

Rowland was engaged to football star Roy Williams, but the pair split in 2005. This is the first marriage for the singer.

She is working on her fifth studio album, which will feature Pharrell Williams.

"I'm at the very very beginning stages of the record," Rowland revealed.

"We're at the point now where we are all talking -- writers [and] producers -- we're all excited. There are fresh ideas coming into the studio right now. We're trying different beats. It's a really great start."
