No Doubt's next single, in America at least, will be 'Looking Hot'.
This is the correct decision.
The 'news' was confirmed by whoever runs the Interscope Promotion Twitter.
In fact, these are the exact words they used: "How Soon IS NOW? US RADIO @nodoubt next single #LookingHot sending out now via efolio."
The allure of new music summed up in one tweet there. (eFolio is Universal's digital music delivery thing, FYI.)
