It seems Robert Pattinson is feeling lonely in London. The "Twilight" actor was recently spotted getting a picture with his fan in the area. However, Pattinson did not look very happy in the picture. Was he missing Kristen Stewart?

R-Patz is in London with his family to spend the holidays. Apparently, he also asked K-stew to join him for holidays but the latter denied, as she is not comfortable with Rob's family.

"While Robert Pattinson did call up Kristen Stewart and invite her to London so that they could spend Christmas together, she turned him down to avoid causing more tension with his family," says a source close to K-Stew to Holywoodlife.com.

Margherita Vitali was the fan with whom Robert Pattinson got photographed with. She later posted the photo with caption, "And then you decide to go out for a beer, and meet Robert Pattinson #RobertPattinson #twilight#luckynight #luckygirl #Londonlife."

Indeed it was a lucky night for Vitali. We hope such lucky nights also fall in Kristen Stewart's kitty. Poor Kristen, reportedly she couldn't join Robert in London due to his family. Kristen knows that Rob's sisters are not very fond of her.

"Kristen would love to see Rob in London but she doesn't want to be the source of any tension between Rob and his sisters. She feels like she's on good terms with Rob's mom after all the cheating drama," says a friend close to the actress in an exclusive report by Hollywood Life.

Robert and Kristen Stewart's relationship is quite fragile at the moment and one wrong step can throw them apart forever. We think Kristen is being sensible in not interfering in Robert's family time.

"If things were different with the rest of his family, she would be there for Christmas, but she still has concerns. The last thing she wants is to bring any drama whatsoever to Rob's world," continued the source.

Let us know what you think about Kristen's decision of not spending Christmas with Robert. Is it good for their relationship?
