"I swear I didn’t mean to break it... Thank you guys for the kind, glitchy welcome ❤️," Aniston wrote alongside a clip from her upcoming series, The Morning Show, in which her character, Alex Levy, gets frustrated and throws her phone down. Her post quickly surpassed 4 million likes and was filled with comments from celeb friends and fans praising her.
Since then, she's been reposting her pals' Instagram Stories welcoming her to the platform. She's also posted a handful of her own IG originals, including her version of a Boomerang, which prove that she's already an IG pro.
Sarah Hyland also shared a sweet throwback of her with Aniston and Paul Rudd from their film Object of My Affection.
"In honor of @jenniferaniston getting an Instagram I’m reposting this picture from almost 24 years ago. Neither she, Paul Rudd, nor myself have aged since 1996. I love ya fake mama! ❤️ #objectofmyaffection," she wrote.
