Kelly Rowland has married her manager Tim Witherspoon in Costa Rica.

The couple announced their engagement last December after they had dated for several years.

Rowland's former fellow Destiny's Child singer Beyonce and Beyonce's sister, Solange, attended the May 9 ceremony after Solange's now-infamous altercation with Jay Z, Beyonce's husband, at a Met Gala after-party May 5.

"It was a quick, simple ceremony -- only around 30 people," a source told Us Magazine about the wedding.

A publicist for the former "The X Factor" judge did not respond to the media outlet's requests for comment regarding the happy event.
