The Babyshambles frontman released a home video showing himself playing guitar while watched by Moss onto the internet in an attempt to drum up interest.
"We're trying to write songs together and trying to get signed," Doherty explained. "People have been saying that Kate's annoyed at the video being posted but she said I should do it.
"It takes a long time to get signed these days and we thought we would post stuff on my website to speed things up a bit. That clip is about a month old and I've got a few more to post online as well."
