Harry Potter star and feminist activist Emma Watson has been spotted having an evening out with a handsome male companion who has now been identified.

The Daily Mail reports that Watson was seen enjoying the company of Cole Cook after a night out at trendy Manhattan eatery The Spotted Pig.

The restaurant is located in New York's hip and LGBTQ-friendly West Village, which is also home to a number of celebrities including Sarah Jessica Parker, Julianne Moore, Daniel Radcliffe, and Hugh Jackman.

Cook is the half brother of Grammy Award-winning singer and philanthropist Alicia Keys — their father is Craig Cook but they each have different mothers.

Cole, who is a businessman, is close to his sister Alicia and it is believed that he works with her husband Swizz Beatz.

As they strolled the city streets, Cook and Watson appeared to be very relaxed and close with each other, stopping to laugh and possibly even flirt a little.

Watson, 29, was wearing black pants and a midriff-revealing top, and over that a black motorcycle jacket.

Looking relaxed and rock 'n' roll, she seemed happy with her male companion.

Cole was dressed casually in a long-sleeved tee and baseball cap paired with ripped jeans and suede boots.

The pals laughed and joked around with each other as they walked, unnoticed by fans or passers-by.

Tuesday is known by New York locals to be the preferred day for Manhattan's celebrities to dine out if they want to be left alone and go unnoticed.

Watson was last seen dating another entrepreneur — Brendan Wallace — who has a background in finance.

Watson has spoken to media about the fact that she intends to keep her dating life private to avoid getting her lovers caught up in the Hollywood circus and to stop encouraging paparazzi to follow her and her boyfriends.
