Michelle Williams, Jason Segel dating - report

michelle-williams-jason-segel-usweekly.jpgHung up on Dawson Leery no more, Michelle Williams has reportedly found a new man -- actor Jason Segel.

The Oscar-nominated "My Week with Marilyn" actress, 31, is currently dating the 32-year-old "How I Met Your Mother" star, reports Us Weekly.

"They are smitten and very serious," a source tells the magazine.

The cute new couple was photographed taking a walk hand-in-hand after dining at Frankie's Spuntino in Brooklyn on March 24. The next day, Segel was seen playing with Williams' daughter Matilda (dad is the late Heath Ledger).

The two have apparently been longtime friends through Williams' bestie and Segel's "Freaks and Geeks" costar Busy Philipps, but it only recently took a romantic turn.

"She hasn't been this happy in a long time," the source says.
