My how things can change in just a few short years, and Lady Gaga is one who can definitely attest to that.

It was not even five years ago when the “Bad Romance” singer was attending New York University, hanging out with friends and going to football games.

Of Gaga - whose real name is Stefani Germanotta - a friend told In Touch, “She looked so different then. She went for more of a tan, sex-bomb look with long curly dark hair.”

And her current fast-paced, super successful life is much different from what it used to be.

The friend added, “She always did all of her homework and was a fantastic student. She cared about her work and would dedicate herself when she had to write a paper.”
