Molly-Mae Hague has offered to pay her sister Zoe's salary after she quit the army.
However, the 26-year-old says she can't accept the offer.
Molly, 23, is said to be worth £6m and has brought her sister onboard at Pretty Little Thing as an influencer.
But Zoe says she's now considering a career in the fire service or close protection sector after leaving her job in the Royal Army Medical Corps.
Addressing her future in a YouTube video, she said: "My last day in the army was the 6th of April so my pay finished on the 6th of April. I had a secure income and now that's stopped and I won't lie, it's hit me that it's stopped.
"Molly's offered so many things to me. She's offered me to help with [fake tan brand] Filter; she's said she'll pay me a monthly wage, but I can't. It's not me. I need to be out and about doing something.
"I'm very lucky she does and she's always offering to get me things, which I'm super super grateful for."
Zoe boasts more than 250,000 followers on Instagram following her sister's stellar success after her debut on Love Island in 2019.
After leaving the villa, Molly became the creative director of PLT and has been branded the 'ultimate influencer', bagging thousands of pounds per social media post.
She then got her sister Zoe a job at the fashion brand, where the 26-year-old has reportedly signed a five figure deal.
Speaking about the ex-army office's burgeoning career as an influencer, a source told MailOnline: "It's a no-brainer.
"Molly-Mae's working relationship with PLT has been a triumph and now bosses are hoping to replicate the same with Zoe.
"The sisters are also looking to collaborate and build on their brand as a family, which could make them millions."
The Mirror has contacted Zoe's representatives for comment.
Meanwhile, Molly could be on her way to becoming the 'ultimate mumfluencer' after welcoming baby Bambi in January.
According to Branding and culture expert Nick Ede, the businesswoman could 'own the space' and even make as much as £2million per year if she makes the right deals.
The expert claimed her baby's unique name could help accelerate her success.
He told The Sun: "Her daughter's name Bambi is brilliant and can be used from a brand point of view.
"It's fun and unique and also has a place in everyone's childhood memories from the Disney film."
