It seems Kristen Stewart can't stay away from Robert Pattinson, even for a day. The "Twilight" actress who left for New York, soon after going on a date with Pattinson, broke down to tears while shooting for a film titled "Anesthesia".

There are few scenes in the film which require Kristen to cry and howl. Her acting in the film was so real that it looked like as if she was missing the "Map to the Stars" star.

She was pictured on the NYC street corner on Nov 4 shooting with the actor Sam Waterston. According to the spectators K-Stew stormed out of an apartment building, dressed in a green beanie and warm coat.

Kristen Stewart reunited with her ex Rober Pattinson last week when she spent a Mexican holiday Dia De Los Muertos together. And if a source to Entertainment website Hollywoodlife.com is to be believed then the couple is on their way to unison.

"Rob and Kristen went to check out the scene at Hollywood Forever Cemetery on Saturday night, Nov. 2.There was a huge celebration for the Mexican holiday "Dia de los Muertos" with tons of costumes and bands. They just mixed in with the crowd and acted like a normal couple just hanging out." A source told Hollywoodlife.

It has also been reported that the couple is spending time at a common friend Shanon Woodward's house. However, Woodward denied any such meeting on the Twitter page today.

"The only secret meetings that have ever taken place at my house involve me and a murder of imaginary crows. Don't worry. My therapist knows." She tweeted.

K-stew and Rober Pattinson were also spotted together days ago at Pattinson's house in Beverly Hills and apparently spent four hours together. It is speculated that Kristen Stewart is Robert Pattinson's true love and he can't imagine his life without her.
