Courtney Love has revealed she took LSD when she was just four-years-old.The singer, the widow of late Nirvana frontman Kurt Cobain, insists taking the hallucinogenic drug at such a young age had improved her mind. Courtney, 42, told Rolling Stone magazine: "Because I was given acid at four, I think my mind was freed. "The wild rocker also spoke about selling part of her stake in Nirvana's music for $50 million dollars. She said: "Before that, I'd saved $4,000. We were almost ready to apply for food stamps. I sold 25 percent of the music to a guy named Larry Mestel who's been great, fucking great. Some of his ideas are a little cheesy. The last thing we want is 'Smells Like Teen Spirit' selling Coca Cola."But if you look at my daughter, and that's who that music is for - that music is for her, ultimately - if it ends up having to be fucking sugarwater, that's what it ends up having to be."I pray to God it doesn't, and I don't think it'd be appropriate. But no one's looking to sell Nirvana songs to Coca-Cola, we're looking to the opposite - eco-friendly green cars, anti-Apartheid, you know all the things we value."Courtney also revealed her and Kurt's daughter, 14-year-old Frances Bean, is a big Kelly Clarkson fan.
