A Baby for Brad & Angelina

01/12/2006 at 06:00 AM EST

Disembarking from a private plane in the capital city of Santo Domingo in the Dominican Republic, Angelina Jolie and Brad Pitt assumed now-familiar Mom-and-Dad positions: Jolie holding 4-year-old Maddox's hand; Pitt toting 12-month-old Zahara. But there was something distinctly different about this scene. Something big. Something round. Something Henri Dominique, an ambassador from the Yéle Haiti relief organization who greeted the glamorous family at the airport, couldn't help but notice. Might Jolie be expecting, he gently inquired?

"Yes, I am pregnant," replied a beaming Jolie, a clingy black tank top hugging what looked an awful lot like a second-trimester bump. "We're due in the summer."

To which Dominique politely offered his best wishes. And to which the rest of the world – fans, friends, paparazzi, bloggers, talk show hosts, economists; is there anyone who isn't in Brangelina's orbit? – will now let out a collective gasp. After endless pregnancy rumors – and just six months after Jolie adopted Zahara from Ethiopia – it's official: Jolie, 30, and Pitt, 42, are having a baby, PEOPLE has learned.

"They're in love and want to create a life together," says a friend. "It's all the things you dream about, [and] they share the same dreams."
