Bad Romance, Telephone, Alejandro and The Fame Monster as a whole are her best work ever. The era was also pretty flawless, and to tell you the truth I think Born This Way is a better album but the era was a little messy so I don't say it's her best. But the Bad Romance video was followed by the Telephone video and then Alejandro, arguably three of her best, who would've thought she would become the mess that she is now?
