Céline Dion's career may have begun in the humblest of settings – singing in her parents' piano bar outside of Montreal – but she would go on to become a Grammy-winning, mega-selling diva who would command the biggest stages in the world.

The youngest of 14 children, Dion shot up the charts outside her native Canada with the 1990 single "Where Does My Heart Beat Now." A year later, she scored with "Beauty and the Beast," but it was "My Heart Will Go On," the theme to 1997's Titanic, that made her a superstar.

But privately, Dion and her husband René Angélil, the singer's longtime manager who discovered her at age 12, struggled to start a family. After a public battle with infertility, Dion gave birth to the couple's first child, son René-Charles, in 2001.

A year later, the new mom moved her family to Las Vegas, where she commenced her five-year show at Caesars Palace, grossing a mind-blowing $400 million. Off stage, Dion underwent another grueling round of fertility treatments in the hopes of giving her son a sibling. The result? The birth of twin boys, Eddy and Nelson, in 2010.

Now back in Vegas, Dion debuted a second show at Caesars in 2011, where the singer says she'll "balance my showbiz life with my most important job: motherhood."
