How Do I Find All The Foreign Keys In A Database

Here is the script which I use always for finding all the Foreign keys in a Database. 

USE AdventureWorks; 
SELECT AS ForeignKey,
OBJECT_NAME (f.parent_object_id) AS TableName,
COL_NAME (fc.parent_object_id,
fc.parent_column_id) AS ColumnName,
OBJECT_NAME (f.referenced_object_id) AS ReferenceTabName,  -- Reference Column Name
COL_NAME (fc.referenced_object_id,
fc.referenced_column_id) AS ReferenceColName  -- Reference Column Name
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
ON f.OBJECT_ID = fc.constraint_object_id
