Brash pop star Pink admits she is often too rough with new husband Carey Hart, after giving him a painful tattoo on his bottom.

The derriere art featured the logo of the former motocross star's new band Social Distortion, but Pink is the first to confess the experience was far from comfortable.

She says, "He complained I was heavy handed."

The Just Like A Pill hitmaker wed Hart in a Costa Rica ceremony in January (06). She was inspired to add to his already bountiful body art after he set up his own chain of tattoo parlours.
