It's no secret that One Direction loves body art. Earlier this week, Zayn Malik and Louis Tomlinson invited tattoo artist John Bahel to their hotel room in New York City to get inked -- again. Bahel tweeted, "I usually don't make house calls but made an exception for #onedirection #zaynmalik #louistomlinson."

Zayn walked away with the letters "MSG" on his right forearm, a reference to One Direction's performance at Madison Square Garden in New York City this week. The letters are just bold enough to stand out below his infamous ZAP tattoo.

During the Madison Square Garden concert, Zayn wasn't afraid of telling the audience how much the experience meant to him. In between songs, Zayn took the microphone to chat with the cheering crowd. "I'm from a small town called Bradford. And let me tell you, things like this do not happen to boys like me," he said.
Louis was also inked on his right forearm, although it's unclear what the design looks like. He currently has a series of tattoos on his right arm, including a flock of birds, a stick figure on a skateboard with the words "OOPS!" and "far away."
Tonight, Zayn, Louis, and the rest of the band will perform at the Z100 Jingle Ball in New York City. Taylor Swift, Ed Sheeran, and Justin Bieber will also take the stage.
