A lithe Courtney Love turned up to kick off Fashion Week after attending a retreat with life coach Tony Robbins. After performing at Hiro Ballroom at One Model Management’s 10th anniversary party, she told us, “I did this Tony Robbins course in Australia, and I added — slowly — two yoga classes and running. My determination was to add something physical. I want to get back to Pilates.” At the after-party at the Electric Room at the Dream Downtown hosted by Nur Khan and DeLeon Tequila, Love told us she met Robbins in the mid-’90s at a meditation session at Brett Ratner’s house. Love was a last-minute replacement for Motley Crue frontman Vince Neil, who canceled Sunday after he fell ill and lost his voice. “This [bleep] ’80s rocker canceled on us at 6 p.m. on Labor Day,” Khan quipped onstage. One Model founder Scott Lipps played drums with Love’s band, Hole, after being quickly approved by Hole’s guitarists during their sound check. “Scott is surprisingly a [bleep]kicking drummer,” Love told us.
