Extra’s Mario Lopez interviewed Britney at Universal Studios today after having to reschedule because of her nauseating helicopter ride on Tuesday.

“We’re up there for 50 minutes, we couldn’t circle anymore because we had to stay in one place… we’re hovering and the helicopter would drop and kept dropping and I was like ‘OH My GOD I’m going to throw up all over everybody,’” Britney said.

She also reveals information about her new Las Vegas show, “Piece of Me,” saying:

“We wanted the feeling of it to be that when people come, they’re in the show with me and they’re really there with me, so we’re going to have a cool set up for them… so it’s a party vibe.”

When asked about the Miley Cyrus controversy, Britney said she gets it.

“I remember that age when I was just transferring into my career and doing more controversial things and the energy that you feel, all this chaos going on and she is on fire right now, she’s just a ball full of energy.”
