While there were no pics from the actual sleepover itself, Paltrow did take to Instagram on Sunday to share a snap of the birthday girl, her bestie Blue, and a few other friends.

"Birthday brunch squad," Paltrow captioned it, using the hashtag "#godsistersandbesties."

Are these not the cutest BFFs ever?

Apple and Blue, 4, were also photographed during a VIP hang in February. The stylish duo chilled at Super Bowl 50, where Beyonce was performing with Martin's band, Coldplay, during the halftime show.

Before Apple's birthday bash kicked off, Paltrow honored her and Martin's eldest child with a sweet throwback photo and message.

"Here she is 10 years ago today on what was her second birthday," the mother-of-two wrote. "Happy birthday, Apple Martin, great love of my life."
