Tycoon Donald Trump has become a father for the fifth time, after his wife MELANIA gave birth to a baby boy today. The 59-year-old billionaire made the announcement in an interview on US TV this morning (20MAR06), just 20 minutes after Trump Jr was born. He told MSNBC's IMUS IN THE MORNING show, "Everyone's perfect. I continue to stay young, right? I produce children, I stay young." The couple have yet to decide on a name for the baby, a younger step-brother for Trump's older offspring, DONALD Jr, IVANKA and ERIC - from his marriage to IVANA TRUMP - and Tiffany, from Trump's marriage to second wife Marla Maples. Trump married Slovenian model Melania, 35, in a star-studded Florida ceremony in January 2005, after a five-year courtship.
