Gwyneth Paltrow reportedly wanted to keep her marriage breakdown secret.

The Iron Man 3 actress - who announced last month she and Chris Martin were separating after 10 years of marriage - was said to have been keen to allow people to believe they had no problems, but the Coldplay frontman felt it was "wrong" to pretend everything was fine.

"It was his idea to announce the split. They had drifted apart, and there was no chance they'd get back together, so he felt it was wrong to keep pretending," a source told The New York Post.

The former couple - who have children Apple, nine, and Moses, eight, together - have been holidaying in the Bahamas since news of their separation was announced. They broke the news with a statement on Gwyneth's lifestyle website GOOP in a post titled "Conscious Uncoupling."
