Oscar-winning actress Gwyneth Paltrow has rubbished rumours that her marriage to Coldplay frontman Chris Martin is on the rocks.

The rumours were fuelled further when the Shakespeare In Love star arrived at the Oscars without Martin.

Paltrow denied the speculations. 'We're a very happy household,' the Mirror quoted her as saying.

'You see people break up, and it seems the ones who are the most public with it suffer the most publicly. It just seems like it invites the whole world in and I just prefer to not do it that way,' she added.
