The launch of the Versace for H&M collaboration was one of most buzzed-about events among party-goers, fashion addicts and shopaholics in recent weeks and when word got out that the event would feature musical performances by Nicki Minaj and Prince, things got pretty hysterical.The evening included a runway show of Donatella Versace's looks for H&M, which included a vibrant collection of her namesake line's classic, splashy prints. The front-row was packed with celebrities, VIPs and fashion icons like Uma Thurman, Blake Lively, Sofia Coppola, Anna Sui, Proenza Schouler, Alexander Wang, Joseph Altuzarra, Chloe Moretz, Stephen Dorff, Chace Crawford, Abbie Cornish, Debbie Harry, Ke$ha and more. The performances were stellar with Donatella rocking out throughout but the real fun started at midnight when the VIP preview store opened and everyone lost their cool grabbing for coats, bags, shirts and accessories. It was high-fashion insanity!
