In April Beyoncé Knowles’ mum Tina and her long-term partner Richard Lawson married in an all-white wedding. The couple and their 300 guests, who all wore white, celebrated the union aboard a luxury yacht moored outside of Newport Beach.

Beyoncé shared a picture on her website of the newlyweds toasting to their marriage with a glass of champagne. Tina, 61, wore a slinky white Romona Kevez design while her groom matched her in an all-white suit, white bow tie and white boat shoes. Beyoncé, her husband Jay Z and their daughter Blue Ivy were among the invitees, as was the singer’s younger sister Solange.
