How do seemingly minor celebs afford lavish lifestyles?

[likemindedarseholes]

Reading a Heat magazine and James (formally of Busted) mentioned living in the Hollywood hills. Also these 'Cribs' style programmes where someone who had one hit or was in one reality show has a great looking house... what's the secret?
Are they rented houses? Did James from Busted invest well? And how do people like Katie Price spend it all, she must have made loads with all the books, perfumes, tv shows? How??

Nowadays, because of the number of underpaid jobs that people in the Arts usually work while honing their craft, a lot (not all) of those at the top had some kind of support while young, or came from wealthy families. So there's probably a fair percentage of them who didn't start from absolute zero.

Strange thing to say and totally untrue

Abraxan I was referring to a PP saying that Matt Willis was apparently able to pay off his mortgage thanks to Year 3000. I googled it and it's only James that's credited with writing it
