Kelly Rowland fears she is "too selfish" to have children.

The singer joked that she prefers sleeping and chilling out on her own to looking after a baby.

However, the 30-year-old does want children eventually.

"I definitely see children in my life but I'm definitely not ready yet," she told UK magazine Hello. "I'm too selfish. [Laughs] I want to sleep and I'm not up for getting up in the night because the kid wants to eat. I like doing things my own way right now, but when I'm ready to share my life with a child, I will."

The former Destiny's Child star also spoke about her Hollywood crushes.

Kelly isn't romantically interested in anyone right now, but admitted she used to fancy 90s band New Kids on the Block.

"Honestly, no. No one believes me when I say that but it's true [that I don't have a showbiz crush]. Growing up, though, I had a crush on New Kids on the Block. I wanted all of them," she laughed.
