Gwyneth Paltrow’s daughter Apple turned sweet sixteen on Thursday, and Paltrow marked the occasion by posting a rare photo of the teen, along with a sweet message.

“I can’t believe I’m actually writing these words but... happy sweet sixteen my darling girl,” Paltrow wrote on Instagram, alongside a photo of her daughter posing on a couch wearing a white floral print mini dress. Apple's father is Paltrow's ex-husband, Coldplay’s Chris Martin.

“You are the light of my heart, you are pure joy. You are wickedly intelligent and you have the best, most dry, most brilliant sense of humor,” the 47-year-old actress and Goop founder continued. “I have the best time being your mom. I love our nightly evening chats when I really get to hear what’s on your mind.”

She also praised her daughter's work ethic. "You have grit and responsibility in spade," Paltrow wrote. "I am so damn lucky to be your mother, you beautiful, kind young woman. Thank you for choosing me. I adore you to the moon and back a zillion times."

Paltrow expressed her disappointment that Apple wasn't able to celebrate with a big party due to the COVID-19 pandemic.

“I’m sorry you are having this particular birthday during these circumstances, but as always with you, you find the best in everything,” Paltrow added.
