Because it’s been reported that her husband Jay Rutland, 34, earned just £3,378 last year.
Tamara, 30, is the daughter of Formula One boss Bernie, who is thought to be worth around £3 billion.
While the couple, along with their one-year-old daughter Sophia, live in a £45 million mansion, figures claim Jay’s company Brigante Business Developments netted him just £65 a week in 2014.
It’s reported that the year before the business was worth £18,131.
But Jay’s apparent lack of earnings hasn’t stopped them living the kind of lavish lifestyle dreams are made of.
In 2013 they married in a £7 million ceremony in France, and earlier this year Sophia celebrated turning one with a party that is rumoured to have cost £70,000.
Before marrying Tamara Jay was a stockbroker, but his career was ended when he was accused of ‘market abuse’.
A spokesperson for Jay told The Sun: “Although this company is still active it had not been trading in the financial year the filing reflects.”
Would the amount somebody earned stop you from dating them?
