They've been rumored to be quietly dating after initially hanging out to make their exes jealous, but one birthday weekend may have been all that was necessary for Selena Gomez and Cara Delevingne.

Selena Gomez Has 'Real Feelings' For Cara Delevingne

The two, who celebrated Gomez's 22nd birthday in St. Tropez in July, were not together to celebrate Delevingne's own 22nd bday in Ibiza this week, as the model-turned-actress posted a snap from her celebrations on Instagram-but Gomez wasn't present for it.

Instead, the model celebrated with BFF Suki Waterhouse, as well as Sophia Kerrison, Scarlett Alexander and Clara Paget, as the ladies hung out on a yacht in the Spanish city, but Gomez wasn't present for the festivities.

Justin Bieber Trying To Make Cara Delevingne Jealous?

"I could not be happier!!!!! Ahhhhhhh we are going to......wonderland! 22 here we come x @sophiaaekerrison @scillywilly @sukiwaterhouse @clarapaget," the model captioned the photo.

Waterhouse also posted some pics of the celebrations, as well as ones of them as they returned home, that showed the girls all having fun, even as they came back to their usual lives.

"Conquer," Waterhouse captioned a shot of the five women as they walked off their jet upon returning home.

And though Gomez hasn't actively shown where she is through her own Instagram page, her relationship status is once again throwing fans for a loop, thanks to a post on her ex, Justin Bieber's Instagram page (that has since been deleted), that shows an intimate kiss between the two.

The photo, which showed him carrying Gomez in his arms as she kisses his cheek, was captioned "Right now everything else is a blur," spurring more speculation that the two were once again dating.

If Gomez is yet again spending time with Bieber, it would mean her alleged plan to make him jealous by hanging with Delevingne worked.
