He’s often been known as the ‘bonus Jonas’ and wasn’t in the Jonas Brothers band… here’s everything you need to know about the fourth Jonas brother- Frankie Jonas.

If you thought there were only three Jonas brothers, we’re about to blow your mind… Nick Jonas, Joe Jonas and Kevin Jonas have another brother, a fourth brother – Frankie Jonas!

Yes, the Jonas Brothers band didn’t include young Frankie, but the 20-year-old is the youngest of the brothers – and he’s already been successful in his own right.

Frankie, who goes by Franklin, is a singer in his own right and has a sound a little different to his famous siblings.

Here’s everything you need to know about Frankie Jonas:

How old is Frankie Jonas?

He is the youngest of the Jonas clan, and is only 22 years old which goes some way to explaining why he wasn't in the band with his siblings – he was just a child!

These days Frankie is crafting out his own solo career and has released his debut EP called 'Sewer Rat'.

Why wasn’t Frankie in the Jonas Brothers band?

There’s no shade to why Frankie wasn’t in his big brothers’ band – he was just a little bit too young at the time, being seven years younger than Nick Jonas!

Camp Rock, the Disney film that shot the J-Bros to fame came out in 2008, so Frankie would have only been 7 years old, which is young even for child star standards!
