Meet Beyoncé’s new stepsister, actress Bianca Lawson

When Beyoncé and Solange Knowles’ mother, Tina Knowles, wed actor Richard Lawson over the weekend, the superstar sisters didn’t just get a new stepdad. They also welcomed a stepsister into the family – and she comes with starry credentials!

Bianca Lawson is not a singer like her sisters, but an actress with many credits to her name. In 1993, at 14 years old, she was cast in Saved by the Bell: The New Class as Megan Jones. Since then, Bianca's ageless appearance has kept her steadily working in Hollywood, landing countless roles as a high schooler or a woman in her early 20s – despite the fact that she's now 36 years old!

Her silver-screen break was on Save the Last Dance, where she played mean-girl Nikki opposite Julia Stiles. More recently, the dark-haired beauty starred in Pretty Little Liars as Maya St. Germain for three seasons before her character was killed off in 2012, after which she guest-starred as the girlfriend of a drug smuggler on Chicago, P.D.

Bianca’s acting resumé was revealed online after it was announced that Tina had wed Richard on Sunday, April 12. The ceremony was held aboard a 140-foot, sun-drenched yacht, which was docked outside of Newport Beach, California.

Just five months earlier, Tina's youngest daughter, Solange, had tied the knot with music manager Alan Ferguson in New Orleans.

Excited for her mother, Beyoncé shared the first photo of Tina's slinky, one-shouldered Romona Keveza bridal gown that featured a knee-length slit. The newlyweds are all smiles in the snap, as they hold glasses of champagne.

In October, Tina opened up about finding love again after divorcing Beyoncé's father and former manager, Matthew Knowles, in 2009. The couple had been together for more than 30 years when they called it quits.
