It's a boy!

It's a baby boy for Donald Trump and wife Melania , the real-estate entrepreneur announced early Monday morning on MSNBC. The beaming father did not divulge the new arrival's name. As is usual with news about Trump, major details are expected shortly. His friend, Katie Couric, made the announcement on the Today show. The Apprentice star, 59, who has four children by his two former wives, Ivana and Marla, was a bit taken aback by the initial news that his new wife was expecting, the couple told PEOPLE last January. "He came home (one day last August), and I told him he'd be a daddy," said Melania, 35, with a laugh. "And his reaction was ... at first he needed to take it in. It was a real surprise. And then he was very happy." Correcting his wife, Donald said: "I expected we were going to have children, so I wasn't totally surprised. But I was surprised by the speed of it. It happened very quickly." (The Trumps were married in a lavish ceremony in Palm Beach on Jan. 22, 2005.) For the first few months, Melania plans to stay close to home. “But eventually we will take the baby with us," she told PEOPLE. Though she hopes to resume her modeling career, she says she'll be picky about assignments, taking only the ones "that I'm passionate about." Whether she's working or not, Melania has already hired a full-time nanny. [People]
