Danielle Brooks and Justin Timberlake are two of the funniest stars in Hollywood, so it’s no surprise that their dynamite energy translated on camera this week. Their plan of attack? Head to brunch.

The pop star joined Brooks and her fellow Orange Is the New Black castmates at Variety’s SAG Awards morning celebration ahead of the show on Saturday. While they mingled, threw up peace signs, and naturally made everyone laugh, actresses like Sophie Turner who, as usual, brought the fashion in a navy lace jumpsuit, and Stranger Things favorites Natalia Dyer and Joe Keery also joined them.

Bella Hadid kept busy in New York, where she celebrated her new DKNY campaign one night, and partied alongside little brother Anwar Hadid at Dior’s celebration of its new fragrance, Poison Girl. Meanwhile, girls ruled the world at the premiere of the final Girls season in New York, where the expected squad included Jemima Kirke, Lena Dunham, Zosia Mamet, and, of course, Allison Williams.

Lily-Rose Depp kept her couture cool in Paris, and McDonald’s—yes, home of the Golden Arches—managed to pull in Olivia Culpo and Justine Skye.
