Since the 'Twilight' star's lone arrival in Berlin, Germany for the filming of her latest venture 'Sils Maria', many can't help but notice her edgier look. 

Apart from dying her reddish brunette hair to an even darker color, her new tattoo was similarly spotted. Kristen Stewart's tattoo bears an eye design which was strategically inked on her right arm.

Stewart donning an all-black garb including her serious facial expressions did not escape the prying eyes of onlookers. An insider tells Hollywood Life that the vampire flick actress is unhappy seeing how carefree her former flame Robert Pattinson appears to be:

"Kristen isn't happy that Rob has seemed to be so carefree filming his next movie, going out all of the time, etc. Does she want him to live a happy life? Of course. But she wishes it looked like he was suffering a bit more. She feels like her exhaustion and heartbreak as a result of the situation is written all over her face, and she feels betrayed that it looks like he's totally cool with everything. It's a cycle of depression for her."

While Pattinson remains mum whether he has indeed moved on, he was likewise romantically involved with Alex Pettyfer's ex-fiance Riley Keough.

The heartthrob's latest advertorial for Dior might add to Stewart's frustration as well. After all, it isn't always easy for someone to see her former flame making out with a stunning supermodel.

If the source's claim goes on, then Twilight fans just might have a reason to hope.
