Mel B plans for old age

There are no flies on Mel B - she knows her looks will fade, and demand for her singing might prove to be fickle. So she's come up with a foolproof investment plan to protect her in old age:

Yes, she's investing in the US property market. Because you can't go wrong with bricks and... say, why have all these people put their furniture out on the side of the street?
