Nothing about Lady Gaga is Original at all. She used music from:
Ace of Base;
Lady Gaga vs. Ace Of Base
One of Gaga's latest singles "Alejandro" bears a striking resemblance to the 90′s Ace of Base hit "Don't Turn Around".
Madonna;
Madonna vs. Lady Gaga -- It's On!
If you noticed a similarity between Lady Gaga's brand new song, "Born This Way," and Madonna's classic track, "Express Yourself," you're not the only one -- seems the Material Girl has noticed it too!

And a young woman, Lina Morgana, whom Gaga was friends with, who later committed suicide.
Lady Gaga -- Proof She Stole From Dead Friend?
The mother of Lady Gaga's deceased friend is taking the singer to task because she feels Gaga stole her daughter's style -- and she's put together a video to try to prove her case. TMZ has obtained the video made by Lina Morgana's mother made to show the similarities between the two singers. The video is set to a song Lina recorded before she committed suicide in 2008. Lina and Gaga were friends before Gaga made it big, according to Lina's mom, Yana -- who claims the two worked together back in 2007.

Salvador Dali
Salvador Domènec Felip Jacint Dalí i Domènech, Marquis of Dalí de Púbol (May 11, 1904 – January 23, 1989), commonly known as Salvador Dalí, was a prominent Spanish surrealist painter born in Figueres.
Dalí was a skilled draftsman, best known for the striking and bizarre images in his surrealist work. His painterly skills are often attributed to the influence of Renaissance masters. His best-known work, The Persistence of Memory, was completed in 1931. Dalí's expansive artistic repertoire includes film, sculpture, and photography, in collaboration with a range of artists in a variety of media.
Dalí attributed his "love of everything that is gilded and excessive, my passion for luxury and my love of oriental clothes" to a self-styled "Arab lineage," claiming that his ancestors were descended from the Moors.
Dalí was highly imaginative, and also had an affinity for partaking in unusual and grandiose behavior. His eccentric manner and attention-grabbing public actions sometimes drew more attention than his artwork to the dismay of those who held his work in high esteem and to the irritation of his critics

The Egg
The egg is another common Dalíesque image. He connects the egg to the prenatal and intrauterine, thus using it to symbolize hope and love; it appears in The Great Masturbator and The Metamorphosis of Narcissus, which symbolized death and petrification. Various animals appear throughout his work as well: ants point to death, decay, and immense sexual desire; the snail is connected to the human head; and locusts are a symbol of waste and fear.

The Metamorphosis of Narcissus
According to Greek mythology, Narcissus fell in love with his own reflection in a pool. Unable to embrace the watery image, he pined away, and the gods immortalized him as a flower.[color=#FF0000[]b] The painting shows Narcissus sitting in a pool, gazing down. Not far away there is a decaying stone figure which corresponds closely to him but is perceived quite differently; as a hand holding up a bulb or egg from which a Narcissus is growing. The egg has been used as a symbol for sexuality in other paintings by Dali.[/b][/color] In the background, a group of naked figures can be seen, while a third Narcissus like figure appears on the horizon. A long poem was written by Dalí to accompany the painting.
