Celestine "Tina" Beyincé-Lawson (born January 4, 1954) is an American businesswoman and fashion designer known for her House of Deréon and Miss Tina by Tina Knowles fashion brands. She is the mother of singers Beyoncé and Solange Knowles, and is the ex-wife of Mathew Knowles, the manager of Destiny's Child as well as Beyoncé and Kelly Rowland until 2011.
Knowles was born Célestine Ann Beyincé in Galveston, Texas, on January 4, 1954, the daughter of Lumis Albert Beyincé and Agnes Derouen. Her ancestry is Creole (African, Native American, and French). Her family roots are from Iberia Parish, Louisiana. She is a descendant of Acadian leader Joseph Broussard. She married Mathew Knowles on January 5, 1980 in Galveston, Texas. She filed for divorce from Mathew Knowles in 2009, stating "discord or conflict of personalities" which prevented them from "reasonable expectation of reconciliation" as the reason. The divorce was finalized in December 2011. Knowles has two grandchildren; granddaughter Blue Ivy Carter from Beyoncé and grandson Daniel Julez J. Smith, Jr from Solange. While in high school, Tina Knowles was part of a singing group called the Veltones, inspired by The Supremes.
Tina Knowles worked as a beautician until 1990 when she opened the salon Headliners, located in Houston. The salon went on to become one of the most famous hair businesses in Houston. Tina's rise to prominence came as costume designer for Destiny's Child. In the early days of her daughter's career, when money was limited, she created outfits that the members wore on-stage and to events. In 2002, she published a book titled Destiny's Style: Bootylicious Fashion, Beauty and Lifestyle Secrets From Destiny's Child in which she discussed how fashion had an impact on Destiny's Child's success. The book was published through the company HarperCollins.
In 2004, Tina Knowles launched the clothing line House of Deréon alongside Beyoncé named after Agnes Deréon. On November 22, 2010, Knowles appeared with Beyoncé on The View to promote her clothing line called "Miss Tina by Tina Knowles". In 2009, she expanded the line to Walmart after it was previously being sold on the Home Shopping Network. Discussing her style of designing for the line, Knowles revealed she aimed to "hide flaws and create a slimming silhouette", adding, "Everything is created like a foundation garment, even the dresses. The pieces are designed to make the woman look leaner and taller." In early 2010, Tina Knowles again collaborated with Beyoncé to open the Beyoncé Cosmetology Center at the Phoenix House in Brooklyn.
