Hi,

I need to make contact with Gwen Stefani (lead singer of No Doubt)
either by email or a mailing address. I would prefer not to have to
make contact via her record label - I basically have a song that I
would like to send to her, but can also point her to the song (which
is a pre-recorded song by a 70s group) in an
email. Can you locate the most direct form of communicating with Gwen?

Thanks,
Katerina

Dear Speck, 

I don't know if it would work - you might not get an answer or get one
of those polite rejections: that really depends on Gwen and the people
she works with.

However, this is the mailing address for fans: 

Gwen Stefani
PO Box 8899 
Anaheim, CA 
92812 USA

Her official site is : 

Gwen Stefani (Official Site)
<http://www.gwenstefani.com/> 

Record Company: 
Interscope Records
2220 Colorado Avenue
Santa Monica, CA 90404 

(You probably have to write c/o Gwen Stefani here. Please note that
Interscope write in their FAQ:
"I'd like to contact one of your artists directly --- can you give me
their contact information?
Sorry, we're not able to release personal information regarding our
artists beyond what you find on this site."
(SOURCE: INterscope Recordds, FAQ, <http://www.interscope.com/help/help.asp#FAQ>). 

I hope this answers your question and I wish you success in contacting
Gwen. Please contact me if you need any further clarification on this
answer before you rate it. My search terms were:
"Gwen stefani" "PO Box 8899", "Gwen stefani" "mailing address", "Gwen
stefani" "mailing adderss", "Gwen stefani" "contact details", "Gwen

"contact details"

No Doubt she won't hollaback.

Try those also:

8th Floor Beverly Hills, CA 90210

or: 

Gwen Stefani c/o Rebel Waltz Artist Management 31652 2nd Ave, Laguna Beach, CA 92651

Also I would try:

T&T Music Records, Inc.
Artist Management Dept.

Fremont, CA 94555, USA

it seems they manage Gwen as an Artist, but they have strict material
submission guidelines. You definitely should check them out here:

Good luck with your search.
