Unsurprisingly, the Titanic actor with an extraordinary career did not have an ordinary upbringing. Leonardo DiCaprio credits his father, George, and his unconventional lifestyle with shaping his outlook and acting career. George used to be a performance artist and comic book distributor when Leo was growing up. Leo's mother, Irmelin Indenbirken, is a German actor and producer. Although she and George divorced when Leo was only one, Leo said he was raised by both parents in a nurturing environment that could be considered "co-parenting" today.
