This is Ireland Baldwin, daughter of Alec Baldwin and Kim Basinger.
She's a model and she instagrams a lot.
She's dating rapper Angel Haze. This is the two of them together:
In this photo Ireland is with Angel and two other people. One of the other people in this photo is Gigi Hadid.
Gigi Hadid and Ireland are besties.
Gigi Hadid's mom is Real Housewives of Beverly Hills star Yolanda Foster.
And her dad is Mohamed Hadid.
You might recognize Mohamed as the super rich guy who randomly pops up on every Bravo TV show including Million Dollars Listing LA, Real Housewives of Beverly Hills and in general hangs out with famous people a lot.
Gigi has several siblings, one of which is Bella, who often shows up in her pictures and is definitely a part of the ~crew~.
Gigi is a model and most recently posed alongside Patrick Shwarzenegger, son of Arnold Schwarzenegger.
Bella is also a model.
And Bella hangs out with Tallulah Willis...
Who is the youngest daughter of Bruce Willis and Demi Moore.
But back to Gigi. She is currently dating the Australian Justin Bieber, Cody Simpson.
And sometimes she hangs out with Ariana Grande's brother Frankie.
She also hangs out with these two ladies. One is the youngest member of the Kardashian/Jenner family, Kylie (we'll get to the other girl in a minute).
Kylie hangs out with Jaden Smith, son of Will and Jada Smith.
And Jaden hangs out with Moises Arias (formerly Rico, of Hannah Montana).
Moises also hangs out with the girl from the above photo that I said we'd get to in a minute.
And ~this girl~ is Hailey Baldwin.
Hailey is ALSO a model.
And her cousin is Ireland Baldwin.
Her dad is Stephen Baldwin, who is Alec Baldwin's brother.
And she often hangs out with Kendall Jenner and Gigi Hadid.
And remember, Gigi and Ireland are best friends. And Hailey is related to Ireland.
Which brings us full circle back to where we started, with Ireland.
Who is also apparantly friends with Lorde.
And now you know about the celebrity spawned teenage crew that rules instagram. The end.
