The 40-year-old "Iron Man" star, who already has two children with the Coldplay singer, daughter Apple and son Mose reveals that her last pregnancy caused her severe depression, reported Daily Mirror.
"Chris and I would love a third child, but I don't know if I could start changing nappies again. Also when my son was born I had terrible depression," Paltrow said.
"It was strange because with my eldest it didn't happen. I was super-happy. But with Moses it took me a year to get out of a hole," she added.
