Director Tim Burton and his long-time actress partner Helena Bonham Carter have separated after 13 years together, a spokeswoman confirmed Tuesday.

A representative for Bonham Carter, the star of the "Harry Potter" movies and Oscar-winning films including "The King's Speech", said the couple had split "amicably."

"Tim Burton and Helena Bonham Carter separated amicably earlier this year and have continued to be friends and co-parent their children," publicist Karon Maskill said.

"We would ask that you respect their privacy and that of their children during this time." Bonham Carter, 48, and Burton, 56, have two children together but never married.

They met when Burton, whose films include "Batman", "Edward Scissorhands" and "Charlie and the Chocolate Factory", directed Carter in 2001's "Planet of the Apes."

Known for their quirky sense of style, Bonham Carter revealed in a 2010 interview with Britain's Radio Times that the couple lived in separate but conjoined properties in London.

"We see as much of each other as any couple, but our relationship is enhanced by knowing we have our personal space to retreat to," Bonham Carter said.

"It's not enforced intimacy. It's chosen, which is quite flattering -- if you can afford it."
