Meghan Markle and Prince Harry are said to have a net worth of some £100 million despite being "cut off financially" by the Royal Family.
During their bombshell interview with Oprah Winfrey, the Sussexes accused Harry's family of failing to provide enough support and failing to understand their reasons for quitting their roles as senior royals.
The 36-year-old duke told Oprah that the couple had to strike lucrative deals with streaming giants Netflix and Spotify because his family "literally cut me off financially" after so-called Megxit.
The deals are helping to fund the family's lavish lifestyle in suburban Los Angeles, including their £10.5 million mansion in a private enclave for the rich and famous, and other things such as security, which the royals have refused to pay for.

The couple are said to have amassed a £100 million net worth thanks to the home's value soaring, their deals with tech giants, and the fortunes left to Harry by his mum Princess Diana and great-grandmother the Queen Mother, the Times reported.
Meghan, 39, Harry and son Archie, who turns two in May, moved into the hillside house in June last year, just three months after the couple said they were taking a step back from royal life to "become financially independent".
In February, it was announced that Harry and Meghan, who is pregnant with a girl and due to give birth in the summer, will not return as working members of the Royal Family and they had been stripped of their last remaining patronages.
Harry told Oprah that he felt "really let down" by his father Prince Charles, saying his dad had stopped taking his calls at one point and there was "a lot of hurt" in their relationship.
The duke said: "My family literally cut me off financially. But I've got what my mum left me and without that we would not have been able to do this.
He added: "All I wanted was enough money to get security and keep my family safe."
He confirmed the rift with his brother Prince William, 38, continues, with "space" between them, but he hopes time will heal their fractured relationship.
As he visited a school in Stratford, east London, William told reporters on Thursday that he plans to speak to his younger brother.
Here is a look at how Meghan and Harry have become a £100 million couple since leaving the UK for California.
Montecito mansion
Harry and Meghan purchased their nine-bedroom, 16-bathroom mansion in Montecito for $14.65 million (£10.5 million) last June after staying in film mogul Tyler Perry's estate.
They took out a $9.5 million (£6.8 million) mortgage, according to the deeds, which list the owner as a trust that shares a postal address with Meghan's Hollywood business manager, the Times reported.
Estate agent Randy Solakian, who represented the builder when the property was sold to a Russian oligarch, said the couple bought at the right time and got a "bargain".
He told the Times that the property market is now booming and the Sussex family mansion might be worth almost three times what they paid.
Mr Solakian added: "It would have been really ugly if they'd paid $40 million (£28.7 million) for it, which is what it's probably worth, but I would say they got a bargain."
The Sussexes gave Oprah a tour of the mansion during the two-hour tell-all, which was watched by 28 million people in the UK and US alone.
Set on a private street with security guards, it boasts everything from a cinema, spa and gym to a separate guesthouse, tennis court and swimming pool.
The couple also have coops for rescued hens, with a sign reading "Archie's Chick Inn".
The enclave of Montecito, in Santa Barbara County, is sandwiched between the Pacific Ocean and Santa Ynez Mountains, about 100 miles from downtown LA.
It is home to billionaires such as Oprah and stars including Katy Perry, Orlando Bloom and Ariana Grande.
But locals say Meghan and Harry are rarely seen out and about.
Harry's inheritance
It is though that Harry has at least £23 million of inheritance money and assets from Diana, the Princess of Wales, and the Queen mother.
Without the money left by his mum, Harry told Oprah "we would not have been able to do this", referring to going out on their own and moving to the West Coast.
Diana's money came in the form of a trust fund, which Harry and William inherited when they turned 30.
Previously, it has been speculated that Harry received about £10 million from Diana's fund.
Before he was "cut off" by his family, the Duke of Sussex received an income of about £2.5 million a year through the Duchy of Cornwall.
Netflix and Spotify deals
The exact value of the Sussexes' deals with tech giants Netflix and Spotify, through their Archewell production and audio companies, isn't known, but they are very lucrative.
Reports have tried to put a dollar amount on the contracts, with varying estimates from industry insiders.
The financial terms have never been disclosed.
It is said that Meghan and Harry were seeking a contract worth as much as £71 million from Netflix.
The Spotify podcast deal is said to be worth £18 million.
Meghan's acting money
Los Angeles-born Meghan, who starred in the TV programme Suits and smaller films before becoming a senior royal, is said to have had a personal net worth of about £3 million.
Previous estimates have suggested Harry's net worth was as much as £28 million.
Harry's other sources of income would include a small Army pension.
Oat milk lattes
Meghan has invested in Clevr Blends, an oat milk latte startup.
Describing itself as a "woman-led, mission-driven wellness company", the firm began as a coffee shop in Santa Barbara and is privately held.
A starter kit, which includes two "SuperLattes" and an "epic" rechargeable frother, sells for $74 (£53) in its online shop.
When the investment was announced last December, Meghan said in a statement: "This investment is in support of a passionate female entrepreneur who prioritises building community alongside her business."
