HOLLYWOOD: Hollywood siren Megan Fox doesn't want to be compared with Angelina Jolie because she is not "serious and stoic" as the superstar.

The 'Transformers' star has frequently been compared to Jolie but despite the brunettes' similar looks and penchant for wild statements, the younger actress insists they are poles apart, New York Times reported.

"People compare me to Angelina Jolie, and she's so serious and stoic. I'm the opposite. I'm not a tigress like Angelina. Of course, people want me to be. But I want to be the contradiction of that," Fox said.

The 32-year-old actress, who recently compared 'Transformers' director Michael Bay to Nazi party leader Adolf Hitler, blamed the Jolie comparisons for people taking her too seriously.

"When I do interviews, I say things that I think are hysterical. But because we live in a world of sound bites, you're not allowed to have a sense of humour. Sarcasm doesn't translate in print at all. And neither does self-deprecating humour," Fox said.

Fox also said she had doubts about her own acting skills, unlike Oscar-winner Jolie.

"I don't know if I'm talented, I don't know what I can do or can't do. I had no skills at all. As a child, I had it in my head that I was supposed to be doing this, and then I did it. But I didn't know what I was doing," Fox said.
