London: Singer Avril Lavigne is sporting a new tattoo designed like a safety pin on her neck.

The pop star made an impulsive decision to visit a tattoo parlour in Hollywood to get a safety pin etched on her neck, a website reported.

The 26-year-old singer wrote on her Twitter page, “Girls day turning into girls night. Should I get a tattoo????”

She kept her fans updated with pictures and dropped hints about the design she was having.

"Here we go... It's comes in handy all the time, it can hurt you, but at the same time keep you together, safety first!" she tweeted during the process.

She eventually revealed the design in a picture, adding the caption, "its a safety pin!!!!!"

"What a great day with my girlfriends. Just being me. Girl time is always necessary. And I got a tattoo," she wrote on Twitter.
