I want more kids with Jay-Z, says Beyonce

London: Beyonce, who is on her Mrs Carter Show World Tour, has revealed that she is looking forward to become a mum again. The 31-year-old singer performed at London`s 02 Arena on Saturday, and while she admitted that she has found it a challenge to juggle her career and look after 16-month-old daughter, she told the Mirror that she would like to expand her brood. The superstar said that motherhood has changed everything and her biggest job now is to protect her child- Blue Ivy . Beyonce said that after giving birth there`s a moment of rediscovery when you are making sure you still have goals and take care of yourself as a woman. "That was something I struggled with - making sure I was still this strong woman and also making time for my child and balancing the two," she said. The singer, who brought her daughter along on the British leg of her tour, has named it the ` Mrs Carter Show World Tour` in a tribute to her rapper husband Jay-Z, whose real name is Shawn Carter. Speaking to the publication just before she was due to go on stage in London, she said that she is calling it that because she feels she has grown and she is a married woman. She said that it is her name, it is who she is and she is proud of it. Beyonce, who has her fourth consecutive No. 1 album with the release of 4 in 2011, also revealed that being a superstar mum is not always easy as she misses being able to go shopping for nappies without pictures from security cameras finding their way online.
