The sexy `Jennifer`s Body` actress has frequently been compared to the `Mr. and Mrs. Smith` star since her break-through role in 2007`s `Transformers`, but despite the brunettes` similar looks and penchant for wild statements, the younger actress insists they are poles apart. Megan, 23, said: "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." Megan - who was caught in a furore after she compared `Transformers` director Michael Bay to Nazi party leader Adolf Hitler - blamed the Angelina comparisons for people taking her too seriously. She said: "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." Megan also said she had doubts about her own acting skills, unlike Oscar-winner Angelina. She told the New York Times newspaper: "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."
