Grep - How to suppress the "Is a directory" line?

Question

When running

grep 'string' *

I'm getting the following messages:

grep: some-directory: Is a directory
grep: other-directory: Is a directory

How to suppress those messages?

Also, redirecting error messages to /dev/null.
I.e. grep 'string' * 2> /dev/null
