Talulah Riley is world's sexiest physicist

London (ANI): Actress Talulah Riley may be dubbed as the 'world''s sexiest quantum physicist" after pursuing an alternate career in science. The 24-year-old Pride and Prejudice star, who stars with Leonardo DiCaprio in her next movie Inception, is studying quantum science at the California Institute of Technology. "I got into physics through pop science and quantum science and ended up being such a quantum groupie," the Telegraph quoted her as telling Esquire magazine.

She added: "I thought if I could learn quickly enough to try and get involved then that would be super-exciting." The British beauty, engaged to South African-American physicist Elon Musk, further revealed she does not favour sex before marriage and plans to have a big family.

She said: "The things I wanted to do from a very early age - ie. get married and have children - precluded a lot of guys my own age from wanting to have anything to do with me. "I was very upfront about it: ''Hi, I'm Talulah - I don't believe in sex before marriage, and I want to have 10 children.''
