With whom did Tim Burton develop a romantic relationship from 2001 till 2014?

Timothy Walter Burton (born August 25, 1958) is an American director, producer, artist, writer, and animator. He is known for his dark, gothic, and eccentric horror and fantasy films.

Burton developed a romantic relationship with English actress Helena Bonham Carter, whom he met while filming "Planet of the Apes". Burton and Bonham Carter have two children: a son, William Raymond, named after his and Bonham Carter's fathers, born in 2003; and a daughter, Nell, born in 2007. Bonham Carter's representative said in December 2014 that she and Burton had broken up amicably earlier that year. It is unclear whether or not they were married; Bonham Carter has used the word divorce when discussing the end of their relationship while other news outlets state that they never married.
