Michelle Williams and Jason Segel shared a romantic Broadway date last night. The “My Week With Marilyn” star was spotted cozying up with Segel at Tony winner James Corden’s show “One Man, Two Guvnors” at the Music Box Theatre on West 45th Street. An audience member told us, “They look very lovey-dovey. She looks so pretty in white, and he’s in a suit.” The pair have been dating for three months and have also been spotted spending time with her 6-year-old daughter, Matilda.
