The 'Sliding Doors' actress - who already has a daughter, Apple, with her husband, Coldplay's Chris Martin - has reportedly revealed the sex of the
unborn tot to friends.
One pal close to the couple has revealed:
"It's definitely a boy!"
The 33-year-old star's mum, Blythe Danner, admits she is delighted to be getting a second grandchild.
She told US magazine In Touch:
"I don't know how much more excited I could be.
"Gwyneth is very serene with Apple. I observe her and she is extraordinary."
Oscar-winner Gwyneth has previously admitted that she wants a big family.
"I would like to have a whole bunch of children.
"I don't mind girls or boys. My mother gets upset because I say I want all girls because Apple is so fabulous."
The 'Shakespeare In Love' beauty also recently told fans she will not be working on any movies in the foreseeable future because of her commitment to being a good mum.
"With another baby on its way, I don't think I will be doing a lot for the next year or so either.
"Having Apple has changed everything for me It's changed the way I see the world - I feel like it's even changed my DNA."
