Gwyneth PaltrowGwyneth Paltrow as said she’s nervous about having more children with husband Chris Martin because her pregnancies have been so rough.

The Iron Man star has two children with the Coldplay frontman, four year old daughter Apple and two year old son Moses but has previously called her pregnancies “a nightmare” and revealed she had post-partum depression.

Now she’s explained she’s torn about whether to go through it all again: “In theory I’d love to [have more children].

“But it’s really hard for me when I’m pregnant - I’m sick as a dog for months.

“Sometimes I think, ‘Oh my God, I want another one right now, I’ll sustain any amount of vomiting or whatever’. And then sometimes I think, ‘Gosh, everyone’s sleeping through the night now’ [so we’ll leave it at that].

“If it’s meant to happen, it’ll happen.”
