A smelly source explains:
"Jen chose her perfume. But other than launching it at Harrods in London, she's done no promotion. No-one knew where to find it and now everyone's lost interest…They can't figure out why no-one wants to smell like Jen."
We're sure her one in-store appearance didn't help, but we don't exactly recall seeing any of those topless ads anywhere either.
