Getting dumped for Claire Danes while seven months pregnant with then-boyfriend Billy Crudup's baby couldn't have been an easy experience, but Mary-Louise didn’t let anyone see her sweat. Not only did she hit the awards-show circuit with a baby bump on display, she won! Ah, sweet revenge. William Atticus Crudup was born Jan. 7, 2004. In 2007, at age 43, the single mom added to her family by adopting a daughter, Caroline, from Ethiopia.
