You know how ignorant your comment is, right?
"Madonna is scared". Scared of what?
Madonna is the best selling female in music worldwide. Even if there's a new popstar in the world, it won't change this fact.
Madonna's MDNA Tour is more successful than Gaga's "Born Reductive High School Music Ball", have you checked the official numbers of both tours on Billboard Box Office? With less shows than Gaga, Madonna's attendance and gross revenue are higher. So what is she afraid of?
Madonna outlasted Janet Jackson, Mariah Carey, Cyndi Lauper, Whitney Houston (while still alive), Debbie Harry - all these women are more talented than Gaga, Madonna outlasted and outperformed all of them. Why would you even suggest Madonna is scared of a wannabe who copies other people's career stunts?
A new popstar will not change Madonna's legacy. Especially a popstar that walks the path opened by Madonna. Lady Gaga is there now, before her, there was Britney and Christina, before them, there was Robyn, and the list goes on and on retroactively. This is not an opinion, this is a fact.
Gaga will not even stay around for too long. You see, in four years, her career is already in decline. Her latest album sold less than the previous ones. Madonna, at the same stage of her career, was on the rise. And this is not an opinion, this is a fact.
