Selena Gomez posted a photo to her Instagram of herself with Kylie and Kendall Jenner at Coachella, and HollywoodLife.com has learned exclusively that after hanging out with the youngest Jenners, she partied all night at a wild Coachella bash!

Just because Justin Bieber, 20, is busy recording, that doesn’t mean that Selena Gomez, 21, can’t have fun without him! It’s Coachella season in California and while the cat’s away, the mice will party — and HollywoodLife.com has all the exclusive details!

Selena Gomez Partying At Coachella After Hanging Out With Kylie And Kendall Jenner

Continuing Selena’s budding friendship with the Jenners, the singer hung out with Kylie Jenner, 16, and Kendall Jenner, 18, all day on April 11, the first day of the first week of the enormous music and arts festival.

However, later on, an eyewitness source tells HollywoodLife.com EXCLUSIVELY that Selena was partying all night long at the Details at Midnight party in Palm Springs House — and Kylie was there, too! Kendall was nowhere in sight.

We’re told that Selena was in good spirits, dancing and having fun without the Biebs and without a care in the world.

Selena Gomez To Appear On Keeping Up With The Kardashians?

Just because they’re likely to move in together, doesn’t mean that they can’t have fun while they’re apart!

Justin, for his part, is hard at work in the studio with Lil’ Wayne, according to his Instagram — when he’s not recording with Selena, of course!

Now that Selena is living in Calabasas, it seems like she’s constantly in the Kardashian clan’s orbit — and we love her friendship with the youngest Jenners. Just recently, Selena was spotted out to lunch with Kendall. Dare we dream for an appearance of Selena on Keeping Up With The Kardashians?

What do you think, HollywoodLifers? Glad to see Selena’s having fun at Coachella, and with the Jenners in tow? And how pretty does she look in that Instagram selfie?! Let us know.
