Chris Hemsworth was "nervous" about cutting her hair.
The 'Blackhat' star, who has two-year-old daughter India and 10-month-old twin sons, Sasha and Tristan, with Spanish wife Elsa Pataky, recently chopped off his signature shaggy locks in favour of a more "practical" style, but admits he "felt like I was losing my powers."
Asked about his decision to go shorter, the 31-year-old Australia actor said: "I was nervous. I'm a Leo so it was a little bit like losing my mane. I felt like I was losing my powers."
But Chris told 'Live with Kelly and Michael' that he has no regrets about changing her appearance, explaining: "It got long and messy and time consuming. It's like photo-shoot hair -- if you have someone following you around doing it for you, it's cool, but it's not practical."
He jokingly added: "I got it backstage in a bag so I'm gonna hand it out."
Chris also felt very uncomfortable while visiting some prisons with his "long blonde pony-tail for 'Thor' " ahead of shooting his new movie, in which he plays a hacker.
He said: "We went to a number of prisons and spoke with inmates. I sort of naively thought I'll go in and do some character study, and then I got to the prison and instantly thought oh what am I doing here."
