Miley, 20, also impressed the show bosses with her strong work ethic.

The source added to the National Enquirer magazine: "And even though she's the most famous person on the planet, she was totally down-to-earth throughout long days of meetings, rehearsals and performances with the 'Saturday Night Live' stars and never displayed an ounce of attitude."
