Kelly Rowland secretly married her boyfriend and manager Tim Witherspoon on Friday, May 9 in Costa Rica.

Kelly Rowland, Tim Witherspoon Wed

Rowland and Witherspoon’s wedding was a small and intimate affair that was only attended by close friends and family of the couple. "It was a quick, simple ceremony — only around 30 people," a source told Us Weekly.

Present for the nuptials were Rowland’s Destiny Child pals Beyonce and Michelle Williams. Beyonce’s sister Solange, who infamously tried to attack her brother-in-law Jay Z in an elevator last week, flew in to Costa Rica with Beyonce following the Met Ball on a private jet. Knowles matriarch Tina was also in attendance.

Rowland announced her engagement last December while making an appearance on The Queen Latifa Show, where Queen Latifa couldn’t help but take notice of Rowland’s sizeable rock on her left ring finger.

"He put a ring on it," she admitted, adding of their relationship, "It's been a while. We've kept it very, very low — for years, to be completely honest."

As for the engagement itself, it happened over Skype while the two were separated by work. "It was so late, I remember we were both just kinda like, honestly, just staring at each other," Rowland revealed. "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."

Rowland has yet to officially confirm her marriage.
