Does Ariana Grande Have Siblings? What Most People Get Wrong

If you’ve spent more than five minutes on the internet in the last decade, you probably know Ariana Grande. The high ponytail, the four-octave range, the Wicked press tour that basically took over the planet—she’s everywhere. But when it comes to her family life, things get a little more specific. People often ask, does Ariana Grande have siblings? The answer is yes. Well, technically, she has one older half-brother who is almost as famous as she is in certain circles.

His name is Frankie Grande.

If you only follow Ariana’s music, you might think she’s an only child because she’s so singular in her branding. Honestly, though, Frankie has been a fixture in her life since day one. They aren't just siblings; they are basically each other's biggest fans. It’s kinda wholesome, actually. They share the same mom, the formidable Joan Grande, but have different fathers. This makes them half-siblings, though they definitely don't use that "half" label in real life.

The One and Only: Frankie Grande

Frankie James Grande was born on January 24, 1983. If you're doing the math, that makes him about ten years older than Ariana. That age gap is huge when you’re kids. While Ariana was still in diapers in Boca Raton, Frankie was already heading toward a career in performing.

He isn't just "Ariana’s brother" either. The guy has a massive resume. He’s been on Broadway in Mamma Mia! and Rock of Ages. He was a finalist on Big Brother 16, which is where a lot of reality TV junkies first met him. He’s a YouTuber, a dancer, and a producer. Basically, the "performing gene" didn't skip anyone in that household.

Are there any other siblings?

This is where the Google searches get a bit messy. Some people claim there are "secret" siblings or distant cousins.

Let's clear that up:

• Frankie Grande: Her older half-brother (same mother, Joan Grande).
• James Marchione: This is Frankie’s half-brother from his father’s side (Victor Marchione). For Ariana, James is technically a step-brother of sorts through the family connection, but they aren't biologically related.
• The "Victorious" Rumors: Back in the day, people were obsessed with the idea that her character, Cat Valentine, had a brother. Fans desperately wanted Frankie to play him. While Frankie did eventually play a character named Frankini on Henry Danger (who was hinted to be Cat’s brother), that’s just TV fiction.

A Bond That Survived the Spotlight

The relationship between Ariana and Frankie is surprisingly tight for two people living in the chaotic bubble of Hollywood. It hasn't always been easy, though. Frankie has been very open about his struggles with addiction.

He’s credited Ariana with essentially saving his life. After the horrific Manchester Arena bombing in 2017, Frankie realized he was too "checked out" due to his substance use to be there for his sister when she needed him most. That was his turning point. He asked her for help, she got him into detox, and he’s been sober ever since.

You’ve probably seen them together on red carpets or in her "7 Rings" music video (he’s one of the people partying in the house). They also share a weirdly specific bond over Harry Potter and musical theater. When Ariana got the role of Glinda in Wicked, Frankie was reportedly sobbing with joy. It makes sense—they grew up singing those songs together in Florida.

Why the "Half-Sibling" Tag Doesn't Matter

In many families, a ten-year age gap and different dads might lead to a distant relationship. Not here.

Joan Grande raised them with a very "us against the world" mentality. Whether it’s supporting Frankie’s LGBTQ+ advocacy work with GLAAD or Frankie defending Ariana against TikTok trolls, they operate as a unit. They even lived together for a while in Los Angeles when their careers were both exploding.

So, if you were looking for a long list of Grande siblings, you won't find one. It’s just the two of them leading the charge.

What to remember about the Grande family tree:

1. Frankie is the only biological sibling (half-brother) Ariana has.
2. The age gap is 10 years, which is why they seem to be in different stages of life sometimes.
3. They share a mother, Joan Grande, but have different fathers (Victor Marchione for Frankie, Ed Butera for Ariana).
4. Both are massive theater nerds, which is literally the foundation of their entire relationship.

If you’re interested in following their journey more closely, Frankie is incredibly active on Instagram and TikTok, often posting behind-the-scenes clips of family dinners with their grandmother, Nonna. Ariana is a bit more curated these days, but her love for her "big brother" is one of the few things she still posts about regularly.

Check out Frankie's recent work in the musical Titanique or his debut album Hotel Rock Bottom if you want to see the talent runs in the family. It's pretty clear that while Ariana might be the global superstar, the Grande family is a two-person powerhouse.

To stay updated on the Grande family, you can follow Frankie's social channels for the most candid look at their sibling dynamic, as he often shares the "real" moments that don't make it into Ariana's polished music videos.
