Miley Cyrus has announced that she will host the 2015 MTV VMAs, two years after her controversial performance at the awards ceremony. To announce the news, the 22-year-old singer dressed up as an alien wearing a sign which read: "MTV won't let me perform so I'm hosting this year's VMAs."Cyrus's sign was a nod to her 2013 performance alongside Robin Thicke which was slammed as too racy.She captioned the picture: "F**k yeah VMAs!!!!! #VMAs on @MTV Aug 30 at 9pm."Cyrus's performance at the VMAs in 2013 caused controversy due to the suggestive performance she put on while wearing a teddy bear leotard and Cyrus has admitted in the past that she set out to shock people.She said: "I know what I'm doing. I know I'm shocking you. When I'm dressed in that teddy bear thing, I think that's funny. I was saying yesterday, I had this obsession about this character that's like an adult baby. Like if you see a baby do something like that it's so warped and weird, but there's something creepily hot about it."So when I'm in that teddy bear suit, I'm like a creepy, sexy baby.But I forget that it's, like, people in Kansas watching the show. That people sit their kid in front of the TV and are like, "Oh, an awards show! Let's watch.'"..
