Oz the Great and Powerful actress Michelle Williams, 32, and The Muppets actor Jason Segel, 33, have called it quits after dating for a year. The low-key couple looked happy while vacationing in Cancun, Mexico last month. But when they quietly ended their romance in early February, it came to a shock for many since they believed Williams would soon be walking down the aisle. A source told National Enquirer, “You should hear Matilda talk – she wants to be a flower girl, and she tells her mom she wants a little sister.” Although Segel was a great daddy figure, the ‘long distance’ thing was putting a strain on their relationship. Segel is based in Los Angeles where How I Met Your Mother is filmed, and Williams lives in New York City with Matilda, her seven-year-old daughter with late actor Heath Ledger, who passed away in 2008. ~E.
