Even after Instagram changed its terms of service - then changed everything back again - last year and everyone became really annoying and melodramatic and said they'd be leaving the app for good, it's still super popular and going from strength to strength, whether you're a posing nobody, a brand, an organisation or a celebrity.
The great thing about celebrities being on Instagram is that we feel like we're REALLY getting a sneak peek into their fancy, showbiz, car crash lives, which is much more appealing than reading unsubstantiated gossip. Well, sometimes.
There are a LOT of cool celebrities using Instagram right now, but here's our pick of the top 10 "teen idols".

Oh and feel free to add your favourites in the comments:
She's a REALLY popular US singer/songwriter, but Swift has been getting a lot of press attention on this side of the pond recently for allegedly hooking up with One Direction's Harry Styles.
