Beyonce's bridesmaid dress at her moms wedding finally revealed.

Beyonce showed where she gets her good genes from as she posed alongside her mother, Tina Knowles in a throwback Twitter picture from her recent wedding.

Tina, 61, tied the knot with actor Richard Lawson, 68, on a yacht on April 12, in Newport Beach, California, with a star-studded guestlist.

33-year-old Beyonce dazzled in the newly released image, which also featured her sister Solange , singer Kelly Rowland and actress Bianca Lawson, who all wore white for the special occasion.

Beyonce, surrounded by a host of lovely ladies in the image, showed off her ample cleavage, wearing a plunging white lace dress - topping off the look with a floral headband.
