Beyonce Steals The Show As Bridesmaid At Mother's Wedding

Usually all eyes are on the bride at a wedding. But when Beyoncé is your bridesmaid, unfortunately that probably won't be the case. Especially when she wears a pretty amazing white lace dress with a plunging neckline.

Bey's mum Tina Knowles just tied the knot with actor Richard Lawson on a yacht off the California coast on 12 April, according to the Mirror.

And Beyoncé's best friend Kelly Rowland has now shared a picture of the day, showing the group - including Kelly, Bey, Tina and Solange Knowles - all wearing white.

Tina - who split from her children's father, Matthew Knowles, in 2009 - looked incredible in a one-shouldered dress with a gold belt.

But Bey kinda stole the show in her lacy frock, which she paired with a floral headpiece.

Kelly uploaded the pic to her Twitter page, writing, "Huge congrats to Mama Tina! To witness so much true love is amazing! Love her so much."

Kelly herself also looked super-stylish in a white cutout jumpsuit, with her hair worn straight and long.

According to the Daily Mail, Tina and Richard had been dating for 18 months before their wedding, but have known each other for 30 years.

Other stars at the wedding included Samuel L Jackson, Michelle Williams and Jay Z.
