Russell Simmons must have been high on veggie juice when he called his pal Courtney Love “a crackhead” for posting nude photos of herself on Twitter. “I think she is a sweet girl . . . It’s probably exciting to be a crackhead, I wouldn’t say I was a crackhead but I did smoke a lot of crack,” he joked at the launch party for his new Oxygen series, “Running Russell Simmons.” “I had fun smoking a lot of angel dust . . . Right now I’m a monk. I’m boring, I’m on a green juice fast at this moment so I’m a little high now. I had a double shot of ginger, which makes you a little flighty.” Love, who didn’t make it to his party at Midtown hot spot Lavo, told us last night: “I’m fairly insulted that he associates me with that drug. What does that mean?” Other guests included Tyson Beckford, Nick Cannon, Petra Nemcova, Gayle King and Rev. Al Sharpton.
