Justin Bieber = Guy who made success showing his "hotness" which is pretty "baby a**" if u know what i mean... His music don't surprise cause anyone can do music and awesome videos but give a look at his shows and interviews than you will know the truth.
Lady Gaga = A girl who said that she would be ******** famous and she did! Elected the most influential woman over the world, she is known everywhere else and we can't lie that this were fruit of hard work cause someone who never used the same clothes two times in a year is freaking rich or much creative. If you don't get what she do, don't worry, just follow this tip: Analyse her shows and interviews cause is there that she will say everything about herself and no one know we better the ourselves!
There is nothing more to say than this but opinions are opinions so, let's just show then, not use them as weapons to hurt others 4laugh
