According to Women's Wear Daily, the designer recently had a relapse and has decided to undergo a second round of treatment for drug and alcohol abuse. Just one day after showing his collection in Paris, Jacobs flew back to Arizona to admit himself back into rehab. "Marc made the right decision. He'd been sober for seven years. When he relapsed, he wanted to deal with it right away. Thankfully, Marc recognised the problem himself and chose to deal with it. Obviously, our prayers are with him," said Robert Duffy, Jacobs' business partner.
