Singer Kelis showed her face at her disco ball friend Damon Peruzzi‘s event, “The Real King of New York Party,” Sunday night (Mar 14) at Juliet Supper Club in New York City.

Earlier this week, the “Acapella” singer went off about an airline on her Twitter because they had lost her luggage and the woman behind the counter wasn’t providing much help.

“I am at airport, sans luggage, not happy. How is it that they ‘lose’ bags? Does that make any sense? Let me answer, no it absolutely does NOT… Oh did I mention I have a 9am call time, which would be fine if I wasn’t still here staring at this empty baggage conveyor belt. Not happy. The good news is, however that I don’t trust these airport scoundrels, so all the glorious treats I had made for video are nicely packed in my carry-on. Still not happy about this.

“And it’s not just the lost (sic) of my stuff that p**ses me off. It’s the person behind the counter’s indignant attitude as though I’m the horse’s a** for wanting my stuff back. Or excuse me naively, blindly optimistically expecting my trunk filled with treasures to come barreling down. That is not the case here. I am too tired to even weep over the [louboutin], westwoods, etc etc that will not be going home with me this morning. Ugh, not happy.”

She was arriving at LAX airport in Los Angeles to shoot the music video for “Acapella,” the debut single from her forthcoming 5th studio album FleshTone, due in stores May 17th. Check out a few pics of Kelis at Domon Peruzzi’s party below…
