The singer has Kingston and 21-month-old Zuma with her husband Gavin Rossdale. Gwen was unprepared for how much being a mother would change her life, admitting it is a hard job. She has decided not to be too hard on her kids and to let them express themselves in their own way, meaning she allows them to pick their own clothes. "He has such a cool style and he really seems to own it," she explained to the July issue of British magazine InStyle. "At that age they like to be in control of everything, so I let him choose. Luckily, everything in his closet is cute, so no matter what he picks, he`s gonna look good. For a while he was into costumes. Now he doesn`t ever want to wear shoes." As well as her musical career the star has a fashion line, meaning it can be difficult to find time for herself. There have been rumours the 40-year-old is pregnant at the moment, but her spokesperson has flatly denied the speculation. Gwen refuses to rule out having another baby, revealing she is yet to decide how large a family she wants. "I don`t know. Having children is the hardest thing I`ve ever done. No one could have prepared me for how awesome it is and how hard," she told the publication. "And having two boys - there`s a lot of energy. I mean, it does seem weird that I don`t have a girl, but I feel like I`m running out of time. I also don`t want to spread myself so thin that I can’t even be good for them. Poor Zuma, he`d be the middle guy. I`m not focusing on it right now, but it`s not up to me anyway, you know? These things are miracles, so we`ll see. Otherwise, the clothes are probably to go to some girlfriend of Kingston`s!"
