This is what i did:

IF EXISTS(SELECT *
          FROM sys.database_role_members AS RM
          JOIN sys.database_principals AS U
            ON RM.member_principal_id = U.principal_id
          JOIN sys.database_principals AS R
            ON RM.role_principal_id = R.principal_id
          WHERE U.name = @username
            AND R.name = @rolename)
EXEC sp_droprolemember @rolename, @username;
