They may not have titles or carry out any duties - but Zara and Mike Tindall have proved to be some of the most popular members of the Royal Family.
The in-demand married couple has signed several big money deals with Zara - a granddaughter of the late Queen - endorsing brands such as Rolex and Land Rover and former rugby player Mike making reality TV appearances. Earlier this month it was reported that Mike, 43, is set for more TV exposure with a stint in the jungle on ITV hit show I'm A Celebrity... Get Me Out Of Here.
Meanwhile mum-of-three Zara, 41, recently starred in a campaign for luxury outdoor clothing brand Musto.
And this had led to reports that the pair could be making around £1million thanks to their lucrative deals. Here we take a look at some of them...
Zara's fashion and jewellery deals
As well as being a former world champion equestrian, Zara has racked up several brand deals, including ones in fashion and jewellery.
Just last week, she starred in a brand new campaign for Musto, a firm she has had a long-standing relationship with - and has been estimated to be worth £500,000.
Branding expert Nick Ede told MailOnline : "Potentially she will have a back end percentage on sales, which can really increase revenue.
"Fashion brands do this to incentivise the talent to promote and wear the brand more as that will increase sales and revenue for both parties."
Meanwhile, Zara also has her own equestrian-inspired jewellery collection with the brand Calleija, with one white and rose gold ring in the collection costing £9,680.
Mike's I'm A Celeb appearance
Meanwhile, Mike, who hosts a successful rugby podcast, is no stranger to reality TV.
He's already appeared on the likes of The Jump and had a stint on a stint on Bear Grylls: Mission Survive.
But the next few weeks could see his most lucrative and biggest appearance to date as he is being tipped to be among the famous faces on I'm A Celebrity Get Me Out of Here this year.
He is reportedly set to become the first ever royal to appear on the show with I TV bosses delighted with their signing and hopeful he will make year's series an "absolute must-watch".
One source told the Mirror: "I would expect Mike to receive between £500,000 to £700,000 to appear on the show - certainly a healthy pay packet."
Zara's partnerships with Land Rover and Rolex
Another way Zara boosts her earnings is through several partnerships - and one of them is with luxury watchmaker Rolex.
She has been a brand ambassador for the company since 2006 and is often spotted wearing their watches.
But it is not the only partnership she has - Zara also has a deal with luxury car maker Land Rover and has appeared in several promotional videos for them.
Mike's promos
However, Zara isn't the only one to have brand ambassador deals - Mike does too.
In 2019 he became one of the faces of Pureis CBD - a company that sells CBD oil products that is thought to have netted him around £50,000.
When asked about his ambassadorial roles in an interview in The Times last year, Mike admitted that "you always worry about money".
He explained: "I was very fortunate that I had a couple of ambassadorial roles, so you know there’s money coming in, but sponsorships won’t last for ever.
"You’ve got to plan . . . and what’s coming down the line in terms of school bills, fees to pay...”
