Courtney Love is advertising electronic cigarettes.

The Hole singer has signed up to become the unlikely star of a new web-based advertisement for NJOY electronic cigarettes in a bid to revamp her unhealthy rock 'n' roll image.

The ad sees Kurt Cobain's widow sitting in a window, puffing on a cigarette, while an older woman comes over to berate her.

She tells Courtney, ''Excuse me. You know you can't smoke in here'', to which the straight-talking star rolls her eyes and replies, ''Relax. It's a f***ing NJOY'', before strutting off.

The 48-year-old blonde was thrilled with the commercial, tweeting, ''I f***ing love'', when people began sharing links to it.

Courtney is famed for her hedonistic lifestyle and excessive nicotine consumption, and has battled drug addiction in the past. The controversial star has a rocky relationship with her daughter, Frances Bean Cobain, who obtained a restraining order against her in 2009.

According to court papers, Frances said: ''[Love] has taken drugs for as long as I can remember. She basically exists now on ... Xanax, Adderall, Sonata and Abilify, sugar and cigarettes.

''She rarely eats ... She often falls asleep in her bed while she is smoking, and I am constantly worried that she will start a fire (which she has done at least three times) that will threaten our lives.''
