My girlfriend is "the nice half of my brain": Radcliffe

London: Daniel Radcliffe refers to his girlfriend as "the nice half of my brain" and says she encourages him when he worries about his talent. The `Woman in Black` actor has been in a relationship with production assistant Rosie Coker for over two years and the 23-year-old said she is always supportive, reported Contactmusic. "She`s like the nice half of my brain - the part of my brain that doesn`t dislike me - that`s her. She encourages me which is nice," Radcliffe said. The actor also said it is easier to date someone who also works in the film industry because they understand the fast paced life. "She knows me so she knows this is what I`m like. She knows I love my job and there`s nothing I would ever do to not be doing my job," he said. PTI
