Carnie Wilson had a “fangirl” moment running into Kristy McNichol, decades after the actress’ retirement.

“Totally fangirling!!!” the singer, 58, recently gushed via Facebook. “Kris ( Kristy McNichol) was a part of my youth. I adored her in her movies … especially ‘Little Darlings’ and ‘The End.’”

The Wilson Phillips member told McNichol, who left the entertainment industry in 2001, “how meaningful her movies are to [her] and [her] bestie.”

Carnie noted in the July 20 upload that she and her pal “were just talking about her … and how special” the 63-year-old is.

Calling McNichol a “gracious sweetie,” she concluded that the “Bionic Woman” star “sure is loved.”

She snapped a selfie with the rarely-seen star, with McNichol smiling in a zip-up jacket and white tee.

Carnie, for her part, sported a patterned top and a black beanie in the cozy shot.

McNichol was a child star, who won two Emmys for her role as Letitia “Buddy” Lawrence on “Family” between 1976 and 1980.

Her other notable TV role included Barbara Weston in “Empty Nest,” a “Golden Girls” spinoff.

She is best known for playing Angel in “Little Darlings” in 1980 and Polly in “Only When I Laugh” the following year.

McNichol was nominated for a Golden Globe for the latter.

When she retired from the entertainment industry, McNichol released a statement reading, “My feeling was that it was time to play my biggest part – myself! I must say that it has been the best thing that ever happened to me. So many fans are disappointed that I’m not currently acting; however, some may not realize that the process I’m in at this time is necessary and vital for my personal happiness.”

She chatted with People about the decision in 2014.

“I was on the big stage between ages 8 and 30,” McNichol explained. “I left show business for a variety of reasons, but a big one was my interest in learning what else there is in life.

“This phase of my life is so good,” she continued. “My home life is happy and serene. I love singing. I also enjoy traveling and seeing the world. One of my favorite stops is Hawaii. I like everything about it and may eventually move there part-time.” 

When asked about plans to return to her Hollywood career, McNichol quipped, “Never say never.”
