I just watched the "Wind it Up" music video (which is better in my opinion than what Gag ever did) and at the end Gwen swallows a G shaped key. I can't help but see so many similarities. Even when "Just Dance" hit the charts I thought it was a Gwen song. Who agrees?
Answer on Did Lady Gaga rip off Gwen Stefani?
I have never seen a similarity between the two personally
