More about: No Doubt

Gwen Stefani has spoken of her disappointment at the lack of commercial success experienced by No Doubt on their 2012 reunion, saying she is 'p*ssed off' after less than spectacular sales of their new music.

The band reformed earlier this year, but singles 'Settle Down' and 'Looking Hot' failed to chart - with the latter selling less than 700 copies and reaching just No.397 in the UK charts. The poor chart placing was even more of a surprise as the track was performed live on X Factor on its week of release.

Now, Stefani has admitted that the lack of success has taken much of her enjoyment out of the band's reunion.

"I have to say it's almost not fun. Completely p*ssed off," said Gwen, reports The Metro. "It's too much at once; the fashion, the records, the children, marriage..."

She also added that she feels bad for disappointing friends, family and fans, adding: "Everyone is relying on me for something. I'm not someone who likes to let people down."

The band were met with a warm reception by critics and fans to their Push And Shove album but later ran into controversy when the video for 'Looking Hot' had to be removed from YouTube due to 'offensive' native American imagery.

The band took to their website to release a statement about the video, writing: "As a multi-racial band our foundation is built upon both diversity and consideration for other cultures. Our intention with our new video was never to offend, hurt or trivialize Native American people, their culture or their history.

"Although we consulted with Native American friends and Native American studies experts at the University of California, we realize now that we have offended people. This is of great concern to us and we are removing the video immediately.

"The music that inspired us when we started the band, and the community of friends, family, and fans that surrounds us was built upon respect, unity and inclusiveness.

"We sincerely apologize to the Native American community and anyone else offended by this video. Being hurtful to anyone is simply not who we are."

The video was directed by Melina Matsoukas, who previously experienced controversy when her video for Rihanna's 'S&M' was accused of being "directly derived" from David LaChapelle's work, leading to a lawsuit.
