Just one day after One Direction hottie Harry Styles got ink'd, his bandmates added to their tattoo collection, too!

Zayn Malik, wearing a "Cool Kids Don't Dance" shirt, left Shamrock Tattoo in Hollywood with his fresh right arm tat covered up. Following him, Louis Tominson also displayed a covered-up left forearm tat.

Pretty soon, these teens will have no more empty space on their bodies!
