Photo Proof! 'Yes I'm Having Brad's Baby!'

- 

The actress was spotted arriving in New York last week, struggling to hide what looked like a pregnancy as she disembarked from a private aircraft. Friends say she’s keen to avoid the spotlight and many suspect she was trying to hide the tell-tale bump as she jetted into the Big Apple for some rest and relaxation.

‘If Jen is pregnant, she is moving heaven and earth to hide it and keep the pregnancy under wraps,’ says a source close to the actress.

‘Right now, Jen is just committed to staying calm and healthy. She’s taken off on a holiday with a couple of close friends to get away from it all. She doesn’t want to run the risk of being spotted in LA, so she’s trying to stay out of the spotlight as much as she can.

‘It looks like this is the baby she’s always wanted.’

But sources say there’s another huge reason for her wanting to lie low – problems with Brad Pitt, who friends have confirmed would be the father of her child.
