Beyoncé and Solange Support Mom Tina Knowles at Her Extravagant Wedding

It's official: Beyoncé's mom is no longer a single lady. Last week, Tina Knowles married actor Richard Lawson in a lavish wedding aboard a yacht in Newport Beach, CA. Following Beyoncé's appearance at Coachella earlier that weekend, the singer was joined by husband Jay Z and daughter Blue Ivy for the fete. Her sister, Solange, also showed her support for their mom, as did Beyoncé's longtime friend and former Destiny's Child bandmate Kelly Rowland, who shared a snap of the bridal party on Instagram. One member of the group was Beyoncé and Solange's new stepsister, actress Bianca Lawson — here's why you already know exactly who she is. According to reports, nearly 300 guests watched Tina and Richard exchange vows on a yacht named Eternity. Bey shared photographer Cliff Watts's sweet snap of the bride and groom on her website shortly after the nuptials. As other pictures of the upscale affair show, the bride and groom matched their guests in all-white outfits.

Tina's second wedding comes over three years since her divorce from Matthew Knowles, Beyoncé and Solange's dad, was finalized in December 2011. Tina and Richard reportedly got engaged in late October, just a couple of weeks before the family gathered at Solange's picture-perfect wedding to director Alan Ferguson. Congratulations, Tina and Richard!
