"Happy birthday @camerondiaz," Paltrow captioned a selfie of the two. "Your wisdom, humor, loyalty, cooking skills, guffaws, and ice cubes in rose get me through my life."

"I adore you with all my ❤️," she continued. "(And yes, we are wearing bibs in this picture)."

Back in June, Paltrow revealed to ET that she was going to take a step back from acting at Goop's Wellness Summit in Culver City, California.

"I just went, 'I can't really say who I am to myself.' Which is a hard thing to face up to," she said at the time. "I felt the need to make myself whole."
