Gendre?

[nancylebov]

One of my friends pronounces genre with a 'd', and I assumed it was a personal idiosyncracy, but I just heard Joni Mitchell pronouncing it the same way. She also says that rock is boogie-woogie played on the guitar, which is the kind of statement I file under "I'm not qualified to judge this, but keep an eye out for evidence one way or the other".

Is "gendre" a regional variation?
