I don`t care how I look: Mark Wahlberg

London: Hollywood actor Mark Wahlberg says he doesn`t care about his appearance. The 42-year-old `Departed` actor said he has reached a stage in his life where he isn`t concerned about how he looks any longer, reportedly. "I`m 42. I haven`t looked in a mirror in ten years. I don`t care how I look. If I have to prepare for a part physically, I will, but I`ve got nothing to prove. I`m not trying to impress anybody," he said. Wahlberg plays a single father in the upcoming `Transformers: Age of Extinction`, and the actor, a father of four, said he liked the idea of being an older character. "If Hollywood had its way, normally in a movie like this, Nicola Peltz, (who plays his daughter) would play my girlfriend. But I wanted to embrace the idea of playing older, of playing what will be my reality in the very near future," he added.
