Are those sirens we hear?

The Weeknd hosted a birthday party for his friend Belly – a rapper in the biz – over the weekend and of course, Selena Gomez was in attendance. It's being reported that the whole thing went down at a private Beverly Hills estate where lots of famous faces showed up. Everyone from Big Sean to French Montana to Ashlee Simpson all came out for a good time. And a good time is exactly what they had!

A source said, Selena and The Weeknd, "were very affectionate," with each other. The insider provided more details about their interaction saying, "They arrived around midnight and partied until 3 a.m. He was snapping a few PDA-filled selfies."

Of course, fans are no strangers to this hot and heavy couple's love life. They have been trying to keep their romance on the down low but The Weeknd recently posted a selfie of the two and we can't help but wonder if it was taken at this exact party!

With no caption, he posted this dimly lit photo and shippers freaked out – naturally.

They are seriously H-O-T and we don't see them slowing down anytime soon. Selena has yet to put the relationship on social media but we don't foresee her waiting too much longer.

There's no telling what went really happened at the party or why it got so out of control but apparently, it was shut down at 3 a.m. by police. Yikes! The details about the whole thing are super vague and we're not surprised. Usually, celebs like to keep trouble out of the public eye especially because Selena and The Weeknd are being talked about literally everywhere lately. From her new show, 13 Reasons Why to his Starboy tour – the last thing they need is law enforcement getting in the way.

Selena is not only super proud and comfortable with her new love life but also can't help but keep getting the message out about her Netflix series. It's a series that could seriously change peoples' lives.

She recently posted a photo with a few of the cast members on Instagram and wrote, "Wish the rest of the crew was with us today. Overwhelmed with the response and love @13reasonswhy is receiving. Thank you to each beautiful person who has watched and talked about the message of our show."

This is super cute. Now the only thing left to do is wait for The Weeknd to publicly support the project. That will REALLY have fans going crazy over their commitment to each other. We love that these two have fun together and are able to hang out in the same circle of friends. We have a feeling this PDA at the party will only continue in the future.

Selena and The Weeknd clearly can't keep their hands to themselves and are over trying to hide their love! Hopefully next time, the police won't show up and shut them down.
