FRANCES BEAN COBAIN has waged war against Lindsay Lohan's younger sister Ali - criticising the teenager for attempting to forge her own career off the back of her sibling's fame.
Cobain, whose parents are Courtney Love and late Nirvana legend Kurt Cobain, is adamant she has never used her mum and dad's celebrity to further her own work.
She has now taken aim at 15-year-old Ali Lohan, after she spotted the teen enjoying VIP treatment at the recent Paris Fashion Week in France.
Cobain has written Lohan an open letter using a series of posts on Twitter.com.
The note reads, "Your (sic) not entitled to anything simply because your sister has a recognisable name. Your idea of fame isn't fame. It's infamy. You want to be famous? Work your ass off and make decisions that could potentially catapult your career into a lasting one. Notoriety for who you are and notoriety (sic) for the work you produce are two completely different things. I understand that you have been brought up in an environment 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."
Cobain adds, "Your career choices, thus far, will transcend a future career as someone who attempted to be famous, but never quite achieved it.
"And if you do, it will be the formality of fame that puts you on the covers of tabloids, while the public idly watches you plummet into the murky abyss shared with the likes of Spencer Pratt & Jon Gosslin who, I'm sure, will steal your money whilst there. I'm ashamed to have to be grouped into the same category of person as you."
