If you watched the Disney Channel Original series "Jonas," you may remember that there's not three Jonas brothers, but four. Yes, the band does only feature the three eldest brothers, Kevin, Joe and Nick, however there's a bonus Jonas. The bonus Jonas is Franklin "Frankie" Jonas who was born in 2000 and first entered the public spotlight when he was just eight-years-old. He'd go on to provide his voice for the English dub of "Ponyo" in 2009 (alongside Noah Cyrus) and make his film debut in "Camp Rock 2: The Final Jam" in 2010.

Since then, Frankie has grown up quite a bit and now, the 20-year-old has found popularity on TikTok. Frankie boasts 1.7 million followers on TikTok and some of his most popular videos show off his burgeoning tattoo collection.

Frankie has become quite the tattoo lover in recent years, catching up to older brother Joe. In a video posted to his TikTok, Frankie showed off his ink thus far, which includes a few stick-and-poke pieces, as well as work done by professional artists.

He's even tried out tattooing for himself, inking the name of a "fan" on his leg on December 26th. That fan happened to be YouTuber and influencer Tana Mongeau, who gleefully shared the video to her own TikTok page. Does the Bonus Jonas have a future in tattooing? Only time will tell.

What do you think of Frankie Jonas's tattooed glow up? Can you believe he tattooed Tana's name on himself? Let us know your thoughts on this story in the comments section on social media.
