Kristen Stewart is Losing Hair over Rob Pattinson Break Up

Actress Kristen Stewart is reportedly losing her hair due to the stress of her break up with Twilight 

co-star Rob Pattinson. Kristen is currently filming a movie in Germany, and many of her friends are trying to get Rob to visit her in an attempt to reduce Kristen's stress. A source says, "[Her friends have] begged Rob to visit her on set.  They fear the stress is getting worse because she's been trying to make contact with him and he's ignoring all of her calls." Rob will not visit her and has been ignoring her calls because he has no interest in giving their relationship another try.
