How Celine Dion amassed her staggering net worth of $380 million

When Celine Dion broke out as a teen star in 1981 with her first record "La voix du bon Dieu," she relied on her then-manager and future husband Rene Angelil to finance it -- by mortgaging his home, no less.

Fast-forward 36 years, and the Canadian superstar has amassed a whopping $380 million, according to Forbes.

The majority of her wealth -- a staggering $260 million -- is due to her lucrative Las Vegas residencies, which she's headlined since 2003. In addition, the pop icon has sold more than 220 million records in her decades-long tenure in the spotlight.

Dion is also a real estate maven in her own right. The songstress and her family own several properties around the world -- in Las Vegas, Florida and abroad -- some of which she's sold or listed following her husband's illness and death last year.

Located on a private Quebec island, Dion's lavish Canadian outpost was listed for $29.7 million in 2014 and just sold for an undisclosed price in February after a few price chops.

The starlet has also been struggling to sell her elaborate Jupiter Island, Florida, property she built with her late husband. Complete with its own water park, Dion initially listed the home for $72 million in 2013. After her husband died last year, she lowered the asking priced to $45.5 million, and it's now sitting on the market at $38.5 million.
