Gwen Stefani is finding it hard to juggle her No Doubt touring commitments with motherhood - she's "exhausted" from overworking herself.

The singer reunited with the band for a tour following a five-year hiatus during which she released two platinum-selling pop albums as a solo artist.

During that time, Stefani also had two children - Kingston, three, and Zuma, 10 months - with husband Gavin Rossdale, and worked hard on her clothing line L.A.M.B.

However, Stefani is struggling to keep on top of all her business ventures and look after her two young kids.

She says, "I am exhausted. I'm not going to lie, with the babies, and the band, and the records, the tour, designing. But I'm so grateful we're still able to do this."
