Well, yea Kurt is worth a hell of a lot of cash. Franny is going to be one happy gal when she turns 18. But as for
Courtney, I dont think she is worth shit on her own. I doubt she gets anything for Hole royalties, etc.
Of course, with Kurt's money she's living the high life, but if she didnt have his money she'd be nothing. Basically, she'd be asking Franny for cash when she turns of age.
