One person who won't be invited to the wedding? Courtney Love. Frances no longer speaks to her mother, thanks to her crazy antics. Case in point: In April 2012, Courtney tweeted that former Nirvana drummer Dave Grohl had sex with Frances because he's "sexually obsessed" with Kurt, a lie that Frances was quick to deny. "While I'm generally silent on the affairs of my biological mother, her recent tirade has taken a gross turn," she said in a statement. "I have never been approached by Dave Grohl in more than a platonic way. I'm in a monogamous relationship and very happy. Twitter should ban my mother."
