But there's another Jonas brother that made a rare appearance at Nick's wedding over the weekend and a certain picture is opening people's eyes to his existence...
Here's the picture from the wedding I'm talking about.
Because look...
There he is, the other Jonas brother.
The Bonus Jonas AKA Frankie has always been around but has kind of disappeared over the last 10 years or so.
"Hi, I'm here."
Apparently people had no idea that Frankie even existed.
This person baked a cake and celebrated his existence.
Shock and awe all around. Shock and awe!
According to my extensive Frankie Jonas research, a bitch is 18.
He also went to his brother's weddings because he's related to them.
Oh, and he was also one half of late '00s power couple: Boah Cynas.
That's basically all I know.
So, if you knew about the Bonus Jonas then congrats. If you didn't, now you do.
