MARY J. BLIGE has given up her plans to have children, after falling in love with her stepkids. The singer took on husband Kendu Isaac's three kids - aged 20, nine and eight - when the pair married in December 2003, and she now considers them her own. The 37-year-old says, "It's great being a stepmother. It has changed me. Because it's not all about me anymore. "I don't need to have children to love them. It's like a miracle. These children really love me and I really love them. They even call me mum. I don't need to have a baby."
