Michelle Williams is single again. Sources confirm to Us Weekly that the 33-year-old Dawson's Creek alum and boyfriend Dustin Yellin have decided to end their relationship after one year. Wiliams and Yellin stepped out together for the first time in May 2013, and since then duo kept their short-lived relationship very low key. Williams, who currently stars as Sally Bowles in Broadway's Cabaret, previously dated Jason Segel for one year in 2013 and was married to late actor Heath Ledger from 2004 to 2007. In April of 2013 the Oscar-nominated actress told Paper magazine that her 8-year-old daughter Matilda was her number one priority. "Raising the kid is the work, yeah. And it's amazing, and it's the ultimate creative act," she said. "That's my side project and my center project."
