Allocating memory with "new"

I have a question about the new operator.  The syntax for it is:

	int * pointer = new int;

which says that "pointer" points to a type int variable.

My question is why is "int" needed twice?  I know it's needed from a 
syntax standpoint, but I don't understand what additional information 
the second int really provides.  Doesn't the first int already tell you 
that an int type value is going to be stored at the "pointer" address? 
Can you ever have,

	int * pointer = new double

or something like that?

Thanks for any feedback on this.
