New Delhi, Mar 10 : Gwen Stefani's husband Gavin Rossdale has candidly revealed that he and his wife bathe together in a bid to save water and help the environment.

Gavin, who has two sons with Gwen, Kingston, 2, and 6-month-old Zuma, insisted that every family should adopt the same technique to do their bit for the environment, reports The China Daily.

"All families should bathe together. It''s the least they could do!" Gavin said.

Meanwhile, Gwen revealed that she and Gavin have a new nickname for Kingston because he is currently going through a troublesome stage.

"Kingston is in that terrible twos. Gavin calls him Sid Vicious. He''s like, ''You gave birth to Sid Vicious.'' He''s definitely got an attitude and Zuma is the opposite. He''s like this cool, laidback, easy-going guy - is that always how it is?" Gwen said. (ANI)
