We aren't sure if this is what Elsa meant when she sang, "Let It Go" ...

Courtney Love admitted in an interview with the UK's Sunday Times that she lost a fortune of money as a result of drug addition, legal fees and frivolous spending -- but doesn't appear to be sweating it.

Kurt Cobain's widow said, "I lost about $27 million ... I know that's a lifetime of money to most people, but I'm a big girl, it's rock 'n roll, it's Nirvana money, I had to let it go. I make enough to live on, I'm financially solvent, I focus on what I make now."

Well ... we guess that's a positive outlook on losing almost 30 MILLION DOLLARS!

The troubled singer also said that her drug addiction to first cocaine and, later, crack also had an affect on her money. "I had to run very fast to look after my money and I felt cocaine helped me do that. So I started taking cocaine and that turned into nine months of crack."

Crack is whack, Court! Didn't anyone ever tell you?
