Donald Trump's wife Melania gave birth Monday morning to a baby boy, "The Apprentice" star told MSNBC.

"Everyone's perfect," Trump said in a telephone interview about 20 minutes after his fifth child was born.

Trump said his 35-year-old wife endured about eight hours of labor and was "very happy and it's really great."

"I continue to stay young, right? I produce children, I stay young," the 59-year-old real estate mogul said.

Trump said they had not yet decided on a name for the newest family addition.

Trump, 59, has four children with his ex-spouses, Ivana and Marla.
