It was love at first tour date when Gavin Rossdale's band Bush and Gwen Stefani's No Doubt toured together in 1995. Just over a decade later, they were married and Stefani was giving birth to son, Kingston. In 2008, they had another son, Zuma, who, according to reports, got a mani-pedi on his third birthday. They definitely produced two cute kids, but future rock stars? We'll just have to wait and see.
