Madonna's song and video "Express Yourself", both released in 1989. Lady GaGa has really ripped of a lot from this one.
1. Madonna's hair and makeup.
2. The "Alejandro"-video.
3. Some of the outfits/looks is complete knockoffs.
4. The message of the song, is the same as.. Well, a lot of Lady GaGa's songs.
5. Last but not least, the  melody and "background sounds" is way too similiar to Born This Way.
