NEW YORK (AP) _ Donald Trump's wife gave birth to a boy Monday, the billionaire developer announced.
``Everyone's perfect,'' Trump said in a telephone interview on MSNBC's ``Imus in the Morning,'' about 20 minutes after the arrival of his fifth child.
Trump said the new baby was already making him feel younger.
``I continue to stay young, right? I produce children, I stay young,'' he said, adding that the couple has not yet decided on a name.
Melania Knauss Trump was in labor for eight hours with her first child.
The tycoon's first wife, Ivana Trump, is the mother of Donald Jr., Ivanka and Eric, who are all in their 20s. Preteen Tiffany is the daughter of Trump's second wife, Marla Maples.
Knauss Trump is a model and commercial actress. The couple married in January 2005.
The Slovenian-born model has appeared in numerous print ads and graced the covers of Vogue and British GQ magazines. Trump's reality show ``The Apprentice,'' is in its fifth cycle.
