Elon Musk isn't the only member of his family with entrepreneurial expertise.
Although the 50-year-old Tesla CEO is known for being the richest person in the world, it appears that business acumen runs in the family.
Despite many of us knowing about Elon and his many ventures, the SpaceX founder actually has two younger siblings - 49-year-old brother Kimbal Musk and 47-year-old sister Tosca Musk.
And while older brother Elon is making his fortune from cars and space travel, Tosca has a more NSFW business model.

Tosca is actually the co-found and current CEO of Passionflix, a romance entertainment streaming platform and production company.
Per news.com.au, Passionflix offers its audience a range of TV and movie adaptations from some of the world's most popular erotic fiction and romance novels.
Available on any device, the subscription-based service provides users with a range of flicks in a variety of ranchy categories, including NSFW (Not Safe For Work), Toe Curling Yumminess, Passion and Romance - or for the more temperate user - Oh So Vanilla and Mildly Titillating.

Subscriptions are available for just $5.99 per month, users get unlimited access to exclusive and original content.
And it's currently turning out to be a successful venture, with Tosca telling The New York Times that Passionflix has already raised nearly $22 million in early funding, with the CEO hopeful to increase that figure even more.
Speaking to Decider about her company, Tosca: "We want you to go through a rollercoaster of emotions and then end with a happier, hopeful ending.
"You’ve had your busy day, you’ve had whatever crises that you’ve had to deal with, and at the end of the day, you want to sit there with a glass of wine or a cup of tea and you just want to enjoy this emotional ride that you’re going to go through, knowing that everyone’s going to be fine in the end, not murdered or destroyed in some horrible way. But they’re just going to come out in the end, and you’re gonna cry, you’re gonna laugh, and then you’re happy."
Passionflix even creates its own movies for subscribers, with Tosca sometimes directing behind the camera.
Speaking of having an intimacy coordinator on set for the more steamier scenes in the movies, Tosca revealed: "When we have women and men in some extremely sensitive, intimate moments, not having anyone there to help guide or be able to be there for them to talk to is bad. I think we should definitely have somebody for them to talk to."
She added: "I’m so sensitive to how women’s bodies are portrayed and how men touch women. It’s so specific to me that oftentimes people would consider me more of an intimacy coordinator. Even when our intimacy coordinators are on set, the actors asked that I be there while they coordinate a lot of the movements."
"If you have a really good and sensitive intimacy coordinator, you’ll have a much more comfortable set," she said.
