The former Spice Girls singer - who is a mum to Phoenix, 12, and four-year-old Angel from previous relationships, and is stepmother to husband Stephen Belafonte`s six-year-old daughter Giselle - wants the gender to be a "surprise", and she hasn`t even bought many accessories in preparation for the arrival of the couple`s tot. She told People magazine: "It`s nice to have something left to surprise yourself. You get everything neutral - not too much stuff until the baby arrives. "I`m really so behind with all that stuff. With my other two, I just waited until they were born and [then I] sense what works and what doesn`t." The 36-year-old beauty is expecting to give birth in a couple of weeks and she is eager to meet the tot. She added: "It would be nice to happen sooner rather than later." Mel - who is a judge on the Australian version of TV singing competition `The X Factor` - admitted she isn`t concerned having another baby will add to her workload. She said: "I got back [to Los Angeles] a month ago - my home visits [for the show] were over the weekend so they flew to me. My home visits were at home which was quite nice. I love work. I love doing what I do and if I didn’t, I wouldn`t do it!"
