Kristen Stewart is losing her hair over Robert Pattinson...literally.

Stewart is losing her hair from stress over her Robert Pattinson breakup, a new report claims.

Stewart, 23, is devastated after her breakup with Robert Pattinson. ...and shocking new photos show the actress with a definite bald spot. Kristen Stewart's hair is falling out from the stress-Robert keeps ignoring her calls, and although she's filming a new movie in Berlin, she can't focus on her work.

Back in July 2012, Kristen cheated on Robert and she 's still paying the price...and so is her health.

Kristen's friends are so worried about her that they have flown to see her in Germany-they plan to take her on a yoga retreat near Berlin to help her get over Rob.

Friends say Kristen's been trying to call Robert and he keeps ignoring her calls....and the stress has her sleepless.

One source said,

It was Rob's decision that the two of them not communicate for a while. Rob felt like it was just too difficult for the two of them to move on if they kept in contact. They both want to be able to talk one day, but it's still too soon and there are too many raw emotions from both sides involved. They both continue to have the utmost respect for each other and love for each other. When they were on speaking terms, it would always eventually lead to tears and it was just too painful for both of them.

Uh-oh.

Do you think Kristen Stewart's hair is falling out?
