Former Disney queen Vanessa Hudgens was a "complete disaster" after filming her controversial new film Gimme Shelter.
The 25-year-old actress' friends were left "concerned" for her when she wrapped the movie because she had immersed herself so much into the role of homeless pregnant teenager Apple, she had lost her sense of self and was in "a bit of a mess".
The ex High School Musical star said: "I didn't really know who I was - Vanessa was gone. I came home and I was a complete disaster.
"My best friend is still so concerned about me when she thinks about that day because I was just a bit of a mess. I wasn't really comfortable in social situations and my self-esteem was super low 'cause I had no hair and I had put on all this weight, so physically I didn't feel attractive. And I was single."
However, Hudgens had an easy way to feel herself again.
