No Doubt reveals Push and Shove album cover

The four portraits of No Doubt's members that appear on the cover were photographed and then made into paintings by Los Angeles street artist El Mac.

The artist told Billboard, "It was a month and a half of non-stop work - barely sleeping, barely doing anything but just painting. It was an epic job for me.

"It's a tricky photo-realistic way of painting the patterns because they have to look right up close but have a different experience when you look at them from far away. There was a lot of back and forth."

Push and Shove is released September 25.
