Their super luxe Italian getaway may be over, but things are obviously still sizzling between Selena Gomez and The Weeknd. And while Selena may be working out her feelings for her ex Justin Bieber through her newest song, the Biebs has instead decided to go with some shady snark to address her new relationship.

Selena Gomez and The Weeknd

While Selena and The Weeknd kept relatively low profiles during last night鈥檚 Grammy Awards hoopla, the duo both made an appearance at Rihanna鈥檚 after-party held at Hollywood鈥檚 1Oak nightclub. Although they arrived separately, the two reportedly spent most of their time together, dancing and cozying up at the VIP table before leaving in the same chauffeured vehicle around 2:45am.

Selena鈥檚 former bae, on the other hand, spent the evening with some buddies and chatting with fans via Snapchat. Deciding to fill them in on his 鈥渇avorite song of the moment,鈥 his answer was a sarcastic, 鈥溾橲tarboy鈥 by The Weeknd.鈥 As his friends burst out in laughter, Justin called it a night by saying, 鈥淲e gotta end it now, y鈥檃ll. Y鈥檃ll, that was too funny.鈥

We wonder if Selena agrees.
