Did you know that Lena Dunhan and Taylor Swift are good mates? And did you know that back in the 90s, Stella McCartney used to hang out with P Diddy? Did you also know that Cara Delevingne got a bunny rabbit this week?
We discovered all of these incredible facts, and many others, thanks to many a celebrity sharing their pictures on Instagram.
Case in point: Victoria Beckham, who is now on her way back from showing her latest collection in Singapore, demonstrated that she hadn't lost her dancing skills by throwing an old-school Spice Girls move as she made her way through the airport.
Other highlights included Madonna hanging out with Sting and Tupac from back in the day, Zooey Deschanel and Lea Michele taking a selfie together, and Beyoncé and Solange sharing cryptic pictures of each other (we'll never stop thinking about the lift incident).
But perhaps the best image this week was of James Franco wearing a t-shirt which had pictures of James Franco on it. Of course he did.
Take a look at all the pictures below.
