The actress also penned a heartfelt message for her little girl in honor of her special day.
Gwyneth Paltrow and Chris Martin's daughter Apple turned 13 on Sunday, and the proud parents celebrated with ice cream -- a whole museum of it!
The Oscar winner took to Instagram to share a look at her and her ex-husband standing outside the Museum of Ice Cream in Los Angeles, alongside the birthday girl and her younger brother, Moses, who turned 11 last month.
"Best Apple's birthday/Mother's Day EVER at the @museumoficecream," Paltrow captioned the cute family shot, adding, "SO FUN."

The museum, located in downtown L.A., has been described as something akin to Willy Wonka's fantastical chocolate factory. Visitors get two free ice cream samples with the price of admission, and there is even a sprinkle pool, which is exactly what it sounds like.
Paltrow also penned a super sweet message for her daughter, which she posted alongside a beautiful snapshot of her young doppelganger.
"Happy 13th birthday, you gorgeous human," she wrote alongside the pic. "You light up every room, my heart, the world. You. Are. Everything. I love you, schnapps."

Aside from Apple's b-day, the family also celebrated Mother's Day on Sunday, and Paltrow shared a pic of the sweet surprise her little girl left for her in the form of a post-it note left on her coffee mug, which read, "You mean a latte to me."
The actress also shared a black-and-white photo of her own mom, celebrated actress Blythe Danner, in honor of the special day.
"Happy Mother's Day to this amazing beauty and all moms everywhere," Paltrow wrote.
