Kendall Jenner, Rita Ora and Wiz Khalifa hit the GQ and Armani Grammy Party

Musicians and celebrities including Miguel, Rita Ora, Arnie Hammer, Darren Criss, Mark Ronson and Wiz Khalifa feted the Grammys at GQ and Giorgio Armani’s first annual post-Grammys party last night at the Hollywood Athletic Club.

Jason Derulo and Josh Groban arrived around midnight from the Warner Music Group party and after being introduced for the first time, naturally snapped a photo together. Groban confided, “I like this party. I actually like it better than my own record label’s party because you can actually talk to people here.” Derulo seemed to be a bit out of sorts at first but then pointed to his drink. “I’m better now,” he said.

Khalifa, who arrived without his adorable two-year-old son whom he brought to the Grammys, stood by the bar with a group of friends, while Janelle Monae took photos with Ricky Martin and Armani Executive Vice President Roberta Armani. Monae, who is in town to perform at tomorrow night’s Stevie Wonder tribute concert, dressed in an all-red Armani suit and hat, but admitted she isn’t that concerned with what her clothes say about her. “I don’t really think too much about what I’m wearing,” Monae shrugged, mentioning she was popping in here on her way to Common’s personal afterparty.

Questlove, in town for Jimmy Fallon’s week of taping The Tonight Show in LA, hovered near Martin for a few minutes, asking someone if he thought the “Livin’ la Vida Loca” singer would remember him. Before he could find out, Martin exited at 1 a.m., just as Ronson and Rita Ora showed up and hugged hello. And while the Roots leader left to catch a flight back to New York, members the Kardashian-Jenner clan finally arrived.  Kendall and Khloe made their entrance, but their appearance was quick, only pausing to get their photo taken before they headed out to hit the after party circuit.
