FEAR NOT -- the Hilton family is NOT poor ... in fact, Paris' parents tell TMZ the fact they can take a $10 million equity line out of their Bel Air mansion shows they've still got TONS of cash.
TMZ broke the story -- Rick and Kathy Hilton got approval for a $10 million credit line last month ... and we all wondered why the hell such a super-rich family would need the extra dough.
But yesterday at LAX. they explained the whole thing -- saying, "You do these things for investment purposes." Rick says the move is a "good thing" ... because, "That means we have a lot of equity in our home."
