An 'adorable' night out for Michelle Williams and Jason Segel

Michelle Williams and Jason Segel just keep getting cuter and cuter.

The duo - who has been dating since this spring - took Williams' 6-year-old daughter out for a "totally casual" dinner at Alma Restaurant in DUMBO on Sunday night, an eyewitness told amNewYork.

"They were adorable," the witness said. "They just seemed like a normal family out for dinner."

Not only was Williams, who lives in Brooklyn, paying attention to her daughter - bringing crafts in her bag to keep Matilda occupied - Segel "was very cute and attentive to Matilda," the source spilled.

The trio ate chips and guacamole and tacos, and Williams - wearing a blouse, denim shorts, sneakers and sunglasses - had a margarita and Segel - in a button-down, jeans and sneakers - drank a beer.
