Eccentric soul star Macy Gray doesn't have a clue how much she's worth - because she never keeps track of her money.

The I Try singer burst onto the music scene in the late 1990s and she has raked in millions of dollars in album sales ever since.

But Gray, who has also had bit parts in movies Spider-Man and For Colored Girls, insists she is so disinterested in the money side of fame, she doesn't even look at her pay cheques.

Plugging in her name in search engine celebritynetworth.com, she exclaimed to Reuters, "Wow! It says here I'm worth $38 million (£23.8 million). But I don't know where they got that figure from, because I don't even know how to figure that out. But if it's right, I'd go cash that in right now and go shopping."
