Jennifer Aniston "really upset" Angelina Jolie is pregnant?

Jennifer Aniston is "really upset" Angelina Jolie is pregnant.

The former 'Friends' star, who divorced Brad Pitt in October 2005 following
five years of marriage, is said to have taken the news of Angelina's alleged
pregnancy extremely badly.
A source close to the actress said: "Jennifer is putting on a brave face,
but inside she is really upset. She wasn't prepared for how she'd feel when
she saw the pictures of Angelina and her bump.
"It took her by surprise because it was further proof of just how much Brad
has moved on with his life compared to her."
Jennifer, 38, also resents Angelina because she never had a child with Brad.
The source added to Britain's Star magazine: "Jennifer is desperate for
kids. She can feel her biological clock ticking and is scared that she has
left it too late. She keeps saying that she wishes she'd had kids with Brad
and that, if she had, maybe things would have worked out differently.
"Splitting up with Brad was the hardest thing Jennifer ever went through, so
hopefully she'll get over this latest hurdle. She's made of strong stuff."
Angelina - who has three adopted children, Maddox, six, Pax, four, and
Zahara, three, and a 20-month-old biological daughter, Shiloh, with Brad -
is rumored to be pregnant with twins.
