New couple

Michelle Williams dating Jason Segel??? 

 The new couple Michelle Williams and Jason Segel recently spotted.

 A source tells Us Weekly that the longtime friends have fallen hard for each other. "They are smitten and very serious," the source says. "[Williams] hasn't been this happy in a long time."
 The source's claim is backed up by new images of the two, which show Williams and Segel strolling hand-in-hand through Brooklyn's Carroll Gardens on Sunday, where they dined at Frankie's 457 Spuntino restaurant. "He put his arm around her and made her laugh as they walked," a source tells the magazine. "[They] seemed very relaxed."

 Segel, 32, and Williams, 31, were recently photographed taking a stroll through the city hand-in-hand after having dinner at Frankie's Spuntino March 24. A witness told Us that the "How I Met Your Mother" star put his arm around Williams and "made her laugh as they walked." The next morning, Segel was even snapped spending time with Williams' daughter with late beau Heath Ledger, Matilda, 6. The new couple was also reportedly spotted dining at L.A.'s Chateau Marmont last month, as well as at West Hollywood's Comme Ca March 16. Though the two are going strong, distance could eventually pose a problem since Segel is still based in Los Angeles and the "My Week with Marilyn" star is rooted in New York. Still, they are "trying to make it work," a source tells Us. "She hasn't been this happy in a long time." The new couple is said to be longtime friends through Williams' best friend and Segel's "Freaks and Geeks" costar Busy Philipps.
