A woman who has been dubbed as the "world's cheapest millionaire" has opened up about her somewhat unexpected spending habits...

Because, despite her enormous wealth, she chooses to spend virtually none of it.

There's living frugally, then there's living like this woman.

Here's the full story...

Now, how would your life change if you were to become a millionaire?

Admittedly, most of us share the generic dream of how we'd choose to spend our millions.

​Flash cars, huge mansions, and designer clothes often spring to mind...

As do private jets and luxury vacation homes.

Champagne would more than likely be a permanent fixture on your home menu...

As would caviar and lobster (that's what rich people eat, right?)

Many people also insist that they would donate generously to worthy causes.

Though I'm not sure exactly how many would stick to this promise if they were to come into millions of dollars...

​Anyway, the prospect of becoming a millionaire is sadly just a pipe dream for most of us...

So we simply have to make do with hearing the stories of luxury from real life millionaires, instead.

However, not all of these millionaires lead such exciting lives.

As stated earlier, one millionaire has recently spoken out about her unexpectedly thrifty spending habits, and to say that people are puzzled would be an understatement.

Appearing on TLC's Extreme Cheapskates, fifty-year-old Aimee Elizabeth revealed just how scrimpy she is with her fortune.

TLC

Aimee, who lives in Las Vegas, is worth a staggering $5.3 million but restricts herself to a monthly spending budget of just $1,000. ​

She doesn't have any mortgage or rent payments to worry about...

TLC

Because her house was given to her by her ex-husband, Michael, following their (seemingly civil) divorce.

She claimed that she has worked out ways to save money in all aspects of her life...

TLC

Explaining:

"I keep my water heater turned off, I need twenty-two-minutes to heat it up enough to get a shower so I turn it on every morning when I get up. I set it for twenty-two-minutes so I know exactly when my shower's ready because God forbid I waste another minute on that water heater."

The multi-millionaire believes that this little trick saves her around $80 a month.

However, there's one aspect of her saving tactics that many people can't get on board with...

TLC

She eats cat food.

Aimee confessed to eating cat food to save 30c on buying tins of tuna.

The cat food, which is labelled "chicken and tuna dinner in light gravy" makes for the perfect tuna substitute... Apparently.

But Aimee doesn't care what her sceptics think.

TLC

"When I go to these extremes I think people see it and it annoys a lot of them but I don't care. It saves money."

Each to their own, I suppose!
