Stefani addressed the new group during an appearance on Jimmy Kimmel Live! on Tuesday (February 16), and shared her view that No Doubt members Tom Dumont, Tony Kanal and Adrian Young aren't replacing her with Havok, reports Radio.com.

"They're doing a side project," she told the late night television host. "They wanna be in a punk band. It's not No Doubt. All the guys from No Doubt are doing a new band".
