We Betcha Didn't Know That Beyoncé's New Stepsister Is Famous: Meet Actress Bianca Lawson!

Singer's mother just married the TV star's father over the weekend

Beyoncé and Solange Knowles need to make room for more star power in their family!

The two singers are now stepsisters to Bianca Lawson, after Tina Knowles tied the knot to her longtime beau Richard Lawson over the weekend.

Bianca may not be as famous as Bey and Solange (yet!), but she has had roles on some of the most popular TV shows around.

That's right, the stunning 36-year-old got her start in 1993 on Saved by the Bell: The New Class and has appeared on Pretty Little Liars, 2 Broke Girls, The Vampire Diaries and Teen Wolf.

Tina and Richard wed in front of just a few lucky guests, including Blue Ivy, Jay Z, Solange's husband Alan Ferguson and her son Julez, on a superyacht dubbed Eternity in Newport Beach.

Bey shared the first photo of her mama and stepfather on her website, showing the bride wearing a stunning Romona Keveza gown and the groom in an all-white tux.

This marks the second marriage for 61-year-old Tina, who was previously married to Matthew Knowles.

After divorcing in December 2011, Tina, began dating the 67-year-old actor, who is best known for his work on All My Children and the 1982 film, Poltergeist. 

There's no doubt there was a ton of talent in the family to begin with, but now even more so!
