Heartthrob Harry Styles has added yet another tattoo to his growing collection.

The 'More Than This' singer has been seen with a new piece of body art, although it's considerably smaller than his other pieces.

Styles got a small 'A' inked on his inner elbow and hasn't yet spoken out about the meaning behind it, but his mother's name is Anne Cox so it could be an initial in tribute to her.

Recently, the One Direction lads spoke to the Tumblr blog Storyboard about the progression of their career as a boyband and revealed that their level of success was something they would have never imagined:

"None of us could obviously ever have imagined this just two years ago. I don't think anyone could have seen this coming to be honest."

"I don't think there is anything hard about having such a dedicated fan base. It is actually great to know that there are people out there that love what we do since we put so much hard work into it.
