It's official: Beyoncé's mom is no longer a single lady. Last week, Tina Knowles married actor Richard Lawson [1] in a lavish wedding aboard a yacht in Newport Beach, CA. Following Beyoncé's appearance at Coachella [2] 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 [3], 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 [4] 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 [5], 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 [6], 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 [7]. Congratulations, Tina and Richard!
