Gwyneth Paltrow’s look-alike daughter is 21.

The Goop creator celebrated Apple’s milestone birthday with a touching Instagram slideshow full of never-before-seen snaps.

“To the light of my life, my ray of sunshine, my hilarious, brilliant, best buddy. Happy 21st birthday!!” the actress, 52, gushed. “You are exceptionally kind and utterly wonderful.”

Paltrow went on to write that she is “incredibly proud” of her eldest child’s “strength” and “intellect,” also praising Apple’s “goofiness” and “big laugh.”

“You are just the best. The absolute best. Thank god for you, Apple Martin,” the “Shakespeare in Love” star continued.

“I cannot wait to see what this next chapter brings for you. Love, Mama.”

The social media upload included a video slideshow, featuring numerous photos of the birthday girl through the years.

The snaps ranged from throwback baby photos to mother-daughter selfies.

The footage also included pictures of Apple with her dad, Chris Martin, as well as Paltrow’s husband, Brad Falchuk.

The Oscar winner’s A-list pals celebrated Apple in the comments section, with Reese Witherspoon wishing the Vanderbilt University student a “happy birthday.”

Kate Hudson, for her part, wrote, “Oh honey, this gets me right in the tummy 😢 Happy 21st Apple sweet!!!! 🍎”

Apple was born in May 2004, one year after Paltrow and Martin, 48, got married in Santa Barbara, Calif.

The former couple welcomed son Moses, now 19, in April 2006.

Paltrow and the Coldplay frontman have been co-parenting their little ones since they “consciously un-coupled” in 2014.

The exes are now empty nesters as Moses left home for Brown University last year. Apple, meanwhile, began her freshman year of college in 2022.
