No Doubt are competing to see who takes the most nannies on tour.

The 'Don't Speak' hitmakers kick-off their 'Summer Reunion Tour' on May 16 and because the majority of the band are parents, they will need extra help.
Lead singer Gwen Stefani said: "I think we're going to sleep a lot less than we ever have. Normally, you sleep the whole day, which was my favourite part about touring, but that's a thing of the past. We get to see a lot more of the country, though, because we're actually leaving the hotel room."
Drummer Adrian Young added: "We have a bet about the nannies. Who can score the most nannies within the band? We haven't started it yet, but I'll make some predictions when we're off camera."
Gwen recently revealed she was dreading going on tour as her eldest son Kingston will not be joining her full-time and will instead split his time between Gwen and her husband Gavin Rossdale.
The 39-year-old blonde - who will be accompanied by her eight-month-old boy Zuma - said: "Kingston is going to be hopping back and forth between me and Gavin. Me and Gavin are used to being away from each other. But with Kingston it is going to be a whole different level of pain. It's going to be really hard."
