Beyoncé's step-sister, 39, shares pics with biological mom who is also an actress

Beyonce's 39-year-old step sister shares a photo of her and her biological mother, who also worked in the entertainment industry as an actress.

Bianca Lawson came from a famous family even before meeting the Knowles and her superstar siblings. Her half-brother is Marvin Gaye III, and her mom is Denise Gordy, niece of Motown founder Barry Gordy.

On her Instagram, she recently shared a throwback photo of her and her mom when she was just a kid to pay tribute to her lovely mom. She looked all glammed up in a sailor-themed dress, while her mom smiled beside her in a red turtleneck top and a black beret hat.

Her caption said all that she needed to say about her mom, which was that she was "a real one".

In the picture, Bianca must have been around seven years old, although she was clearly already a beauty since her younger days.

While she is now known as Beyonce and Solange Knowles' stepsister because of her father Richard Lawson's marriage to the singers' mom in 2015, Bianca has made a name for herself way before that.

She was born and raised in Los Angeles, California, and went to Marymount High School just as Kim Kardashian did. Although she came from a well-known family, she made a name for herself by being part of the main cast of "Saved By The Bell: The New Class". She also starred in hit teen shows "Buffy The Vampire Slayer", "Dawson's Creek", and "Pretty Little Liars".

Although Bianca and her mom are extremely close, this has not hindered her from getting close to her stepmom Tina Knowles-Lawson. Tina is all about family, and she shows her love not just for her kids and grandchildren, but even her husband's daughter, Bianca.

Knowles-Lawson has been extremely supportive of the 39-year-old actress, making sure to show her off on social media whenever she can. Whenever she does guestings or has a stunning photo she'd like to share, that's exactly what she does. While she's at it, she also makes sure to advertise Bianca's latest project "Queen Sugar", where she plays the role of Darla.
