Shania Twain has turned a dirt-poor childhood surviving on stale bread into a $590m ($US400m) global real estate empire.

The 60-year-old superstar overcame difficult upbringing, poverty and a high-profile marriage breakdown to build a luxury property portfolio spanning Switzerland, the Bahamas, New Zealand, New York and Florida.

Long before she became the Queen of Country Pop, the You’re Still The One singer grew up in Timmins, Ontario, where her family frequently rationed food and struggled to keep the heating on.

The five-time Grammy winner revealed her mother Sharon and stepfather Jerry Twain financial stress fuelled constant, violent fights at home.

“Our house would shake. Those walls would shake. It gets loud and scary, like a really bad thunderstorm,” Twain revealed on Wild Card with Rachel Martin.

“They would argue over, ‘Can’t pay the bills. Now we’re gonna run out of heat, and now, whose fault is that?’”

Money was so tight that from age eight, Twain sang in local bars to help put food on the table.

When her parents died in a car accident in 1987, the You’ve Got a Way singer took on full responsibility for her younger siblings. She performed at a local resort until landing a record deal with Mercury Nashville in 1992.

Her financial situation changed after marrying music producer Robert John “Mutt” Lange in 1993.

As hits from her record-breaking album Come On Over rolled in, the couple added Château de Sully in Switzerland, to their real estate portfolio.

In 2004, the pair bought Mahu Whenua, a sprawling $31.7m ($US21.5m) retreat in New Zealand’s South Island featuring private cottages, stables and a helipad.

However, her personal life imploded in 2008 when Lange had an affair with her close friend and assistant, Marie-Anne Thiébaud.

The betrayal plunged Twain into severe depression.

“I didn’t want to live anymore,” Twain admitted in an interview with Oprah Winfrey.

In a stranger-than-fiction twist, Twain found solace with Marie-Anne’s ex-husband, Swiss business executive Frédéric Thiébaud.

Thiébaud was the one who initially broke the news of the affair to Twain.

The pair bonded over their shared heartbreak, fell in love, and married on a Puerto Rico beach on New Year’s Day in 2011.

Today, Twain and Thiébaud live in a private estate in Corseaux, Switzerland, overlooking Lake Geneva.
