It's no secret that T. Mills is fond of tattoos. When he stopped by the PopCrush studio to film an interview and a performance, he gave us the details on his body ink, including why he hid his first tat and which design his mom didn't like!

"I had to sit and talk to her for a good 15 to 20 minutes about that one, but that was the only one!" he recalls. "Out of all of these, she wasn't OK with one of them. My odds are pretty good, I'd say."

By the way, when T. Mills gets inked, he's not messing around. Yep, he talked to us about the time he got his leg tattooed during a meet-and-greet in Toronto. That sounds like a stressful situation, but the rapper promises it was fun.

And once, T. Mills even switched roles and inked his name on a fan. Talk about dedication. In this video clip, T. Mills explains where the tattoo is located and even has a special message for that fan.

Watch it all go down in the video above, and see him talk about 'All I Wanna Do' in the clip below.
