The star of the X-Men films has lived in Brooklyn since the summer of 2012.

He's boldly gone where no one has gone before -- except, it seems, a New York pizza shop.

Sir Patrick Stewart surprised and amused his fans on Thursday when he tweeted a photo of himself sipping on a soda, a slice of authentic tomato pie folded in his left hand.

"My first ever pizza 'slice,' " reads the caption. "Please note: the authentic NY fold."

The odds that the 72-year-old star of the X-Men films and Star Trek: The Next Generation has somehow managed to avoid eating a slice of New York pizza in his lifetime seem astronomical -- especially since he has called Brooklyn his home since last summer, when he moved into a $2.5 million duplex in Park Slope.

Still, there's a first time for everything. 

But what are the chances that the actor, donning a Montreal Canadiens cap, has ever tried poutine?

UPDATE: Stewart later tweeted, "To clarify: 1) I've never had a "slice" 2) I've been a Habs fan all of 4 weeks 3) I'm also a fan of Bloomberg's soda legislation."
