United Kingdom, Nov. 27 -- Helena Bonham Carter says Tim Burton was sketching while she was "literally giving birth".

The 59-year-old star - whose 13-year relationship with the iconic filmmaker ended in 2014 - has recalled how her 67-year-old former partner is always doing his own drawings, no matter what's going on around him.

Speaking in new documentary Tim Burton: Life in the Line, she said: "He literally draws his way through life.

"Even if he's with you, he would be sketching. Even through momentous occasions.

"I'd be having a child. He would still sketch. Literally giving birth. We've got our whole lives sketched.

"It was definitely an adventure shared. We went through 1000s of drawings before we decided to call it a day."
