Arnold Schwarzenegger is one of the most famous guys in the world. Seriously, so many people know him. Or, at the very least, they know his famous lines from movies like The Terminator. We love the fact that he’s gone from being a famous movie star to being a political figure, and has since earned the title of 'World’s Sweetest Dad'.

Now, the "sweet dad" thing might be a little tough for those who are on team Maria Shriver (his now-ex-wife) to hear. However, you should trust us when we say that he’s actually done some good stuff for his kids, including Arnold's love child by his former housekeeper, Mildred. This love child's name is Joseph Baena.

Joseph has grown up to be a fine and upstanding young man, even though he still has a few things to hide. We’ve compiled lesser-known facts here, so everyone can find out the truth of Arnold Schwarzenegger’s secret son.

15 He And Arnold Have An Interesting Relationship

“Secret Dad” sounds like the kind of bad television show that could only be found inside the cartoon, BoJack Horseman. However, it’s actually kind of how Joseph Baena was raised by his not-so-secret-anymore father, Arnold Schwarzenegger. Arnold didn’t admit that he was the father of Joseph for a long time.

14 But Not A Bad One

Despite this weird start to the relationship, Arnold and Joseph get along famously! Like, famously enough to post about each other on social media. Who’d have thought that this would ever work out, right?

Arnold has posted about Joseph and vice versa, including when Joseph graduated from college! Truly a proud dad.

13 He And The Rest Of The Family Have Some Tension

Obviously, the kids born to Maria and Arnold are a little bitter about Joseph coming into their lives. Page Six reminds us that it’s not necessarily because they dislike Joseph as a person - it's more because he reminds them of the tough times Arnold and Maria went through. If Joseph was anyone else, we’re willing to bet that they would like him!

12 But He Had Love In Other Places

But don’t worry, he’s still managed to fill his life with love. He found a girlfriend at college and TV Overmind says, “the couple may actually have a greater attraction to one another beyond the looks department. They have been seen together for about a year”. This is good news when it comes to his love life.

11 His Childhood Was Weird

Like, super-weird. Imagine being born to the housekeeper of one of the most famous men in the world, and then growing up around his family without ever being told that you were related by blood.

It’s just wild to try and wrap your head around, and we kind of feel bad for Joseph Baena.

10 And Maria Was The One Who Called It Out

Maria is Arnold’s ex-wife. She was the one who actually noticed just how much the housekeeper’s baby looked like Arnold. Page Six reports, “Maria, who had even attended Joseph’s christening, asked Mildred - who confessed and broke down in tears. Maria, however, encouraged Mildred not to quit right away.”

9 He And Dad Are Identical

Like, ridiculously identical. While the rest of Arnold’s sons don’t seem to share his proclivity for building muscle, Joseph has really and truly taken up the mantle, as we have seen.

We personally think that this is a sign that he was meant to be brought into the world, even if the way Arnold went about it wasn’t great.

8 Which Has Garnered Him Quite A Social Media Following

Remezcla mentions that this kid has huge numbers on all of his social media accounts, and they just keep growing. They mention one picture which specifically inspired people to take notice of him, where Joseph is posing in exactly the same way as Arnold in one of his bodybuilding competitions.

7 It Might Be Getting Him Into Hollywood

His IMDb has a bit of action, just like his dad’s. While he doesn’t seem to have any huge parts coming up, we definitely recognize that he’s interested in the whole Hollywood things. Plus, we’re sure there’s an Arnold biopic on the way which Joseph could star in.

6 He’s Humble, Despite Being A Celebrity

Let’s be real: Arnold is a huge celebrity and a staple of contemporary Western culture. He’s one of those celebrities who hasn’t disappeared over time, despite switching to a different career. Joseph naturally has some fame, too, due to the fact that he’s Arnold’s son. But because he wasn’t raised as such for most of his life, he’s really humble.
