Pink unsure of having second child

London: Singer Pink is unsure of having a second child because she feels her daughter would be a violent sibling.

The 34-year-old `Just Give Me a Reason` hitmaker said she does not know if her three-year-old daughter, Willow, with motocross star Carey Hart would want a sibling because she enjoys being in the spotlight, reportedly.

"I don`t know if she would. I think she really enjoys being the centre of attention... I see siblings that are kind of violent toward their younger ones, and I feel like that might be the way she goes with it," she said, when asked if Willow would want a younger sister or brother.

Pink thinks her daughter is already showing strong signs of being like her `reckless` father. "She`s a maniac, she`s an absolute maniac which is all her dad`s fault. I am physical, but I`m cautiously physically. Carey is reckless and Willow is taking after him," she said.
