This past weekend Grammy award-winning R&B artist The Weeknd hosted an exclusive birthday party for childhood friend and fellow-Canadian rapper, Belly. While hours of seemingly endless rainfall definitely threw a wrench in The Weeknd’s “Pool Party After Dark” theme (the pool itself had to be closed up entirely), it didn’t appear to dampen the mood of his guests or doting girlfriend Selena Gomez, who partied until 4am with Grey Goose cocktails like Le Grand Fizz, High Five, Le Melon Mule and Grey Goose VX beneath the protection of a tented bar and dancefloor. Additional notables at the star-studded bash — held at a sprawling estate in Beverly Hills — included Drake, French Montana, Big Sean, Ashlee Simpson, Evan Ross, and Amber Rose.

Gomez and The Weeknd arrived just before 11:40 p.m., socializing with friends Simpson and Ross and making their way around the tented space before holding court at a VIP table next to Belly. Styled with an effortless low ponytail and dark-colored dress that laced-up in the front and back, Gomez spent most of the evening on her feet and in high spirits – chatting vigorously with friends and event staff, alike – whenever she took a rare pause from lip-locking with her man. The two remained affectionate and playful, with Gomez dancing for her beau to YG’s “Why You Always Hatin’?” and The Weeknd snapping a few PDA-filled selfies before they finally made their early morning escape through the pouring rain.

While they enjoyed their time on Friday night, the rest of the party raged on. Drake rolled up to the house in a Maybach with Big Sean. Wearing a black long-sleeve shirt, he toasted the birthday boy with Grey Goose VX and hung by the DJ booth for a bit before chatting with pal French Montana and a handful of girls.
