Sorry fellas, looks like Michelle Williams is off the market again! And it looks like it's more than just a summer fling. The actress has been spotted several times with artist Dustin Yellin including at this year's Met Gala. Michelle may have shown up alone, but witnesses spotted the pair escaping hand in hand. Then on Monday they attended a children's birthday party in Brooklyn Park with daughter Matilda. This is the first romance for Michelle since parting ways with actor Jason Segel back in February.
