Kelly Rowland of Destiny's Child secretly weds in Costa Rica

Kelly Rowland has put on a "Happy Face"! The Destiny's Child alum has reportedly married her manager and boyfriend Tim Witherspoon.

Only a few family members and friends joined them for the hush-hush destination wedding, Us Weekly reported.

"It was a quick, simple ceremony -- only around 30 people," a source told the mag.

"I really plan on it being a very special day between me and my sweetheart," Rowland told E! News back in February. "Whatever we do we just want it to be special and between he and I and just make it something that we both remember and just for us. It's our gift to ourselves."

Though the "X-Factor" judge has yet to confirm the nuptial news, she was spotted days later at the American Ballet Theatre Spring Gala in New York on Monday, according to the Daily Mail. The singer wore a marigold Lanvin dress and slyly kept her hands (and any sparkly rings they might have on them) in her pockets.

The new Mrs. confirmed her engagement back in December when she appeared on "The Queen Latifah Show."

"It's been a while," she added. "We've kept it very, very low -- for years, to be completely honest."

She also revealed that Witherspoon proposed to her via Skype.

This is Rowland's first marriage. She was previously engaged to football player Roy Williams, but they split in 2005, just months before their planned wedding.

Rowland released her latest album, "Talk a Good Game," last year and has begun work on her fifth, which is set to feature Pharrell Williams, Billboard said.

"I'm at the very very beginning stages of the record. 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," she said. "It's a really great start."
