This might be the ultimate sleepover party that every teenage girl would want to be a part of. Pop stars Selena Gomez and Taylor Swift spent a relaxing Saturday night together, technologically joined by their girl pal Demi Lovato.

While enjoying a nice teatime together, Selena Gomez and Taylor Swift decided to invite their close friend Demi Lovato, who was not able to attend their pajama party, via iPhone's FaceTime function.

The "Come & Get It" singer took a snapshot of their fun video chat conversation and took to her Instagram page to post it with the caption following, "Just a Saturday night. Taylor's tea, Demi's laugh. Honestly, can't complain."

The image showed the girls having a blast during their low-key night, as Selena Gomez was holding out her big teacup and letting out a big laugh with the "I Knew You Were Trouble" singer by her side, while Demi Lovato was talking to the pair, comfortably leaning on her couch at home, all smiling.

In addition, the former X Factor judge and her best friend Selena Gomez have been long time friends -- they go way back to Barney & Friends, which is one of their first performances on television. On Saturday, Demi Lovato posted an adorable image of herself and Selena Gomez from their childhood, dressed up as little animals during an episode of Barney & Friends on Twitter.

"OH MY GOD.... YES!! RT @CantStopDelena: @ddlovato @selenagomez This is the cutest thing I've ever seen!!!!!!!!!!!!!!!!" Demi Lovato tweeted.
