Sarah Jessica Parker Reveals Sudden Death Of Beloved Stepfather After Abruptly Leaving Gala Due To 'Devastating' Emergency

Sarah Jessica Parker is mourning the death of her stepfather, RadarOnline.com has learned, after the And Just Like That... actress abruptly left a celebratory public appearance due to a "devastating" emergency in the family.

SJP was set to be honored at the New York City Ballet's 10th Annual Fall Fashion Gala last night and had to skip last-minute.

"Our family is sad to announce that after an unexpected and rapid illness, Paul Giffin Forste passed away yesterday at age 76," a rep for the Sex & The City alum told RadarOnline.com in a statement on Thursday following her swift exit from the event.

"In his last moments, he was surrounded with the love and gratitude of his adored wife Barbara of 54 years, and children, including Sarah Jessica Parker. Paul will be remembered with the spirit of loving kindness which was his faith, his special delight in his 13 grandchildren, and his sustained belief in making the world a more charitable, tolerant, and beautiful place for all," the statement continued.

Forste, a truck driver, married SJP's mother when the star was only 3 years old, according to the New York Times.

Insiders told Page Six that organizers announced on stage that she had to pull out of the event because of a "sudden family situation," sparking concern amongst fans.

Parker serves as the vice chair of the NYCB Board of Directors.

Just one day prior, she and husband Matthew Broderick were all smiles while attending the premiere of Hocus Pocus 2.

The couple was also joined by their supportive twins, Tabitha Hodge and Marion Loretta Elwell, 13.

SJP and her daughters commanded the purple carpet together at the AMC Lincoln Square Theater.

Parker previously spoke about being a mom in show business in a candid interview, revealing she always strived to keep a work-life balance.

"[Parenting] changes you in every possible way, but there's a struggle, there's a conflict that exists, which is you also want to maintain this other part of your life," she explained.

Meanwhile, the fashion designer and her husband are still going strong after 25 years of marriage.
