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.
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."
