Appending same tring to multiple files in one line?

I have a string that I need to append to 3 files.
Say,

$ echo "Hello"

I want to append this �Hello� to three files, file1, file2 and file3.The files are all in different directories and the file names have no common pattern.Can I do it in one line? If yes, how?

echo hello |tee -a /tmp/file1 file2 /other/file3

Aah! Thanks a lot!
