Beyoncé's mom Tina Knowles files for divorce from actor Richard Lawson

Beyoncé's mom, Celestine “Tina” Knowles, is about to be a single lady after filing for divorce from “How Stella Got Her Groove Back” actor Richard Lawson.

The philanthropist, 69, filed Wednesday from her second husband, 76, whom she married in 2015, according to legal documents obtained by TMZ.

The couple split just one day prior, according to the date of separation listed on the documents, which attribute the marriage’s demise to irreconcilable differences.

In addition to requesting the restoration of her surname to Knowles, the “House of Deréon” co-founder requested the court not award spousal support to either party, according to TMZ.

Knowles and Lawson exchanged vows in April 2015 in Newport Beach, Calif., aboard the yacht dubbed “Eternity” — sadly a misnomer for their union.

A source at the time confirmed to the Daily News that Knowles’ daughters Beyoncé and Solange both attended the ceremony, as did the “Single Ladies” singer’s husband, Jay-Z, and then-toddler daughter Blue Ivy.

A second marriage for Lawson as well, he also has two children from prior relationships. Through first wife Denise Gordy, Lawson is the father to Bianca Lawson, best known for roles in “Buffy the Vampire Slayer” and “Pretty Little Liars.”

Lawson is also the father of Grammy nominee Ricky Lawson, best known for credits on step-sister Beyoncé's “Heated” and “Summer Renaissance,” off last year’s “Renaissance” album.

Knowles and Lawson started dating in 2013. The fashion designer split from her singer daughters’ father, and former Destiny’s Child manager, Mathew Knowles in 2011 after nearly 31 years of marriage.
