The boy is the first child for Weisz and her fiancé, 'Requiem For A Dream'
director Darren Aronofsky.
Despite becoming a mum in the same year as winning an Academy Award, Weisz
ruled out naming her first born after the gong.
At the ceremony in March, she said: "We've narrowed it down to a few choices
but Oscar isn't among them."
In January, the 35-year-old actress - who started her career at the ADC
Theatre in Cambridge, England, while studying at university in the city -
revealed she was expecting after finding her ideal man.
She told 'The Tonight Show' host Jay Leno: "I found myself a sophisticated,
educated American. He's not an actor.
"He's travelled the world. He knows where Europe is, unlike a lot of
Americans. He's very cultured, but he's all man."
Meanwhile, Weisz recently revealed that she didn't develop cravings for
bizarre foods during her pregnancy - despite being prepared to eat weird
foods.
She confessed: "I was expecting all the weird things. There's this jar of
pickles sitting in the fridge. It's been there for months and she hasn't
even eaten one."

Weisz, a London native of Hungarian and Austrian parentage, previously appeared in such films as "The Mummy," "Enemy at the Gates" and "Runaway Jury." The dark-haired actress also is a spokeswoman for Revlon cosmetics.

Her next big-screen appearance will be opposite actor Hugh Jackman in "The Fountain," written and directed by Aronofsky. His previous credits include "Pi" and "Requiem for a Dream."

The $35m production, which originally starred Brad Pitt and Cate Blanchett, had been tipped to premiere at this year's Cannes Film Festival but will now open later this year
