Courtney Love's daughter has lashed out at Ali Lohan.

Frances Bean Cobain - Courtney's child with later Nirvana rocker Kurt Cobain - has posted a scathing open letter to Lindsay Lohan's 15-year-old sister on Twitter, in which she states Ali is only famous because of her family connections.

Frances, 17, wrote: "This is my open letter to Ali Lohan. Your not entitled to anything simply because your sister has a recognizable name. Your idea of fame isn't fame. It's infamy. You want to be famous? Work you're a*s off and make decisions that could potentially catapult your career into a lasting one. Notariety for who you are and notaritey for the work you produce are two completely differnt things (sic)."

Frances goes on to accuse Ali of being talentless, adding she is "ashamed" that people think they two of them are alike because they both have famous relatives.

She said: "I understand that you have been brought up in an envirtoment where the idea of fame is easily achievable but, that's not an excuse. You lack the talent, social understanding and credibility to be anything other then infamous. Your careere choices, thus far, will transcend a future career as someone who attempted to be famous, but never quite achieved it.

"People like You ali lohan are rendering the world of true talent by attempting to make your entitled a*s noticed. How is this fair to the people who HAVE artistic integrity, or a mind?

"I would rather die a most painful death the be assoicated with the kind of careere your trying to make for your self (sic)."

It is unknown if Frances and Ali have ever met, although Frances does admit she does not "personally know" Ali in the letter.
