On June 15, the Rachel Green actress took to Instagram to celebrate the Monica Geller star's 57th birthday.
"Happy birthday to this ridiculously special human," she wrote alongside throwback footage of the pals. "Time flies when you're having fun!"
Sharing a more recent photo of the duo, she then added, "Who loves ya baby?"
"There's absolutely no judgment in Court. You'll never feel scolded. She's extremely fair, ridiculously loyal and fiercely loving," Aniston told More magazine in 2014, adding, "I've slept in her guest bedroom a lot. Without giving away too much of my private stuff, all I can say is she's been there for me through thick and thin."
And getting the group back together 17 years after the beloved series ended brought back a lot of emotions.
"Well, Courteney comes in and bursts into tears," Kudrow exclusively told E! News in a recent interview. "Schwimmer pointed this out when we were watching it together, you know like, Thursday night. And I grab a napkin or a tissue, LeBlanc takes it 'cause he's telling a story and doesn't want to skip a beat and starts dabbing her eyes just on automatic. And yeah, that's who we were."
