MTV Spankin' New Music Week: Lady Gaga Shares The Greatest Moments Of Her Career

From an outsider's perspective, it's easy to say what should and shouldn't matter to a pop star. We note the awards, special performances and chart positions. But what matters to the star, themselves? We posed this very question to the incomparable Lady Gaga.

In this very special Spankin' New Music Week edition of "The 5," as The Fame: Monster is finally officially released, Lady Gaga takes us through the five most amazing moments in her career. It's a deeply personal list that touches on the  socio-political causes that are close to her heart (marching on Washington, D.C. for gay rights) as well as the small, personal pleasure of having her little sister dress up as her for Halloween.

Watch Gaga explain her top five career highlights in this exclusive MTV Buzzworthy Blog video, and get an up-close-and-personal look at the human side of Lady Gaga.
