Hard to believe little Samantha Micelli from TV’s ‘Who’s the Boss’ is now a mom, but it’s true — Alyssa Milano gave birth to a son on Wednesday morning.

The 38-year-old actress and her husband, David Bugliari, who’ve been married since 2009, welcomed their first child, Milo Thomas Bugliari. The tot is 19 inches long and weighed in at seven pounds.

While you’re knitting booties for little Milo, you should plan for another pair as well, because Robert Downey, Jr., 46, and his wife, Susan, have announced they, too, are expecting. Although the ‘Iron Man’ star has a 17-year-old son from a prior marriage, this will be his first baby with Susan, to whom he’s been married for six years. Her due date is not yet known.
