Photos: Blue Ivy, Beyonce, Jay Z, Kelly Rowland, Solange attend Tina Knowles' Wedding!

 Beyonce not only attended her mom's wedding—she was a bridesmaid, too!

At the April 12 nuptials of Tina Knowles, 61, and actor Richard Lawson, 68, there was plenty to celebrate.

In new photos from the wedding, which was held on a yacht in Newport Beach, California, Tina's granddaughter (and flower girl!) Blue Ivy shares a sweet moment on the dance floor with her dad, Jay Z.
