Stunning bride! Kelly Rowland looked gorgeous as she said "I do" to her manager and boyfriend Tim Weatherspoon on May 9 in Costa Rica.

The "Kisses Down Low" singer, 33, made it official with her beau over the weekend in a "quick, simple ceremony," multiple sources confirmed to Us Weekly.

Among the 30 people in attendance were her Destiny's Child bandmate Beyonce and sister Solange, who jetted off in a private plane for the nuptials after their Met Gala drama on May 5, when Solange got into a scuffle with Beyonce's husband, Jay Z

Other guests included Carmelo and LaLa Anthony, as well as Destiny's Child singer Michelle Williams and Beyonce's mom Tina Knowles.

The ceremony was held at a private mansion estate and guests stayed in a villa next door. Everyone, including the bride and groom, wore white for the romantic event.

Rowland also donned a veil and held a colorful array of flowers for her bouquet.

This is the first marriage for the singer; she was previously engaged to football player Roy Williams but called off the engagement in January 2005.
