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."

A few notable guests reportedly included her former band-mate Beyonce Knowles and sister Solange Knowles -- she of Met Gala elevator-fight infamy. The sisters set off for the wedding in a private plane after Solange's heated May 5 altercation with her brother-in-law, rapper Jay Z. Their mother, Tina Knowles, and Destiny's Child member Michelle Williams were reportedly in Costa Rica as well, E! News said.

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."

"He put a ring on it," Rowland said, showing off her colossal cushion-cut ring to the studio audience and quoting Beyonce's "Single Ladies (Put a Ring On It)."

"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."

The singer will also appear in Pepsi's "Beats of the Beautiful Game" project, a visual album celebrating soccer that also features director Spike Lee, actor Idris Elba, music producer Timbaland, Grammy-winner Janelle Monae and British singer Rita Ora. It coincides with this summer's World Cup and will be released June 10, according to the Associated Press.
