How Taylor Swift And Selena Gomez’s Friendship Turned Into Sisterhood

It all started back in 2008.

We all know that Taylor Swift's girl squad runs deep, but there has been one girl that has been there since the very beginning: Selena Gomez.

The two became friends in 2008 after both dating the Jonas Brothers and have maintained bestie status ever since, with Selena most recently telling Vogue magazine that Taylor is "my sister."

In celebration of their sisterhood, we decided to look back at the friendship of Taylor and Selena.

  1. Thank the Jo-Bros.

    Taylor and Selena became besties back in 2008 when they were both dating the Jonas Brothers (Taylor was dating Joe; Selena was dating Nick). Selena told The Herald Sun that they instantly clicked and they became "best friends."

  2. First red carpet appearance.

    Back in 2008, the girls hit the red carpet together at the premiere of "Another Cinderella Story."

  13. Taylor Swift doesn't approve of Selena's PDA.

    In 2013, Taylor had a pretty hilarious moment when she made it quite obvious that she wasn't the biggest fan of Jelena as she was caught backstage sticking out her tongue when they showed a little PDA. Hey, if you're best friend can't be honest about how they feel about your BF, who can?

  18. BFF only listening parties.

    Selena showed love for Taylor's album 1989, by posting this adorable Instagram picture and in the caption describing their listening parties that took place in the kitchen, "driving on the pch, windows down," and guess what? They were super exclusive that only the two of them were invited.

  19. Rocking out.

    In 2014, the BFFs decided to hit up The 1975 concert where they danced and sang along to every single word of the bands song, "The City."
