Michelle Williams and Jason Segel are apparently dating, according to Us Weekly:

The unexpected new couple was photographed taking a romantic stroll after a meal at Frankie's Spuntino in Brooklyn March 24. "He put his arm around her and made her laugh as they walked," says a witness. "[They] seemed very relaxed."

The next day, How I Met Your Mother star Segel was snapped bonding with Matilda, Williams' 6-year-old daughter, as she went for a ride on her scooter.

Friends for years through Williams' BFF and Segel's Freaks and Geeks costar Busy Philipps, their relationship only recently turned romantic.

What if Nick Andopolis and Jen Lindley dated?? Am I right?? She would have had to time travel, so.
