Jennifer Aniston shares a rare selfie documenting her friendship with Selena Gomez

They’ve kept their low-key friendship out of the spotlight for years.

But Jennifer Aniston changed that this week when she shared a never-before-seen selfie featuring her pal Selena Gomez, 28.

The 51-year-old Friends star posted the photo, which was taken with their manager Aleen Keshishian, to her Instagram Stories on Wednesday.

She was celebrating Keshishian’s 53rd birthday, though it wasn’t clear if the photo was taken recently or at a past birthday bash.

Selena, who appears to be wearing a sparkling sequined dress and dangling silver earrings in the photo, can be seen throwing her head back for a big laugh.

Jennifer has on a sleeveless black top and shows off a playful soft smile while Keshishian is sandwiched between the two women.

‘Happy birthday @aleenkesishian. We love you,’ she captioned the picture, while also tagging Selena.

The Spring Breakers star later reposted the photo to her own Insta Stories.

Selena and Jennifer gave their fans a glimpse into their friendship back in January 2020, when the Morning Show star filled in as the host of The Ellen DeGeneres Show while Selena was a guest.

Jennifer gushed about her younger friend during a portion of the interview.

‘You’ve always been so sweet,’ she said. ‘You really are a genuine [Friends] fan. It’s amazing. We’ve known each other for years. You’ve been to my house. We’ve had pizza. Girl after my own heart, do we love a pizza or what? We love a pizza.’

‘Yes, we do,’ Selena chimed in.

The duo explained on television that they first got acquainted during a bathroom run-in at a Vanity Fair event.

‘Well, nobody knew who I was,’ Selena recalled, ‘and you were in the bathroom, wearing a black dress.’

Jennifer, who’s known for being a fan of classic black dresses, replied, ‘Okay, weird.’ 

‘And I think we were at Vanity Fair something event, and I was there with my mom, and I walked into the bathroom and I saw you, and you were just like so nice,’ the singer continued.

‘You just walked out of the bathroom and you were going back, and my heart like, stopped. And I freaked out and I ran to my mom and I was like, “Oh my God, I just saw Jennifer Aniston.” I was like, “Oh my God.”‘

The Horrible Bosses actress didn’t seem to remember the brief meeting as well as her friend. 

‘Did I say hello? Did we have a pleasantry? [I was] washing my hands, I hope,’ she joked.

‘Yeah, you were fine. You were everything that I wanted,’ Selena replied sweetly.

Jennifer added: ‘Bless your heart.’

The pals also chatted about Selena’s then-new album Rare, as well as her single Lose You To Love Me, which was inspired by her break-up with fellow singer Justin Bieber.

The actress later had a more official introduction via their manager Keshishian.

In 2015, Jennifer raved about her friend to E! News at the premiere of her film Cake, which Selena had helped promote.

‘She’s just like a little cherub that I feel like I wanna take care of. And we’ve just met through our manager. She’s been extremely supportive and wonderful,’ she gushed.
