Spears was in a helicopter that hovered above her fans in the desert, who were holding cards that formed a picture of her. The singer stepped off the aircraft and said she was feeling sick. After a second — and live — interview with "GMA," she headed back to the helicopter, barely smiling and offering little more than a wave.

Spears, who debuted on the music scene in 1999, has released seven platinum-plus albums. She has more than a dozen Top 10 hits, including "Toxic," ''Gimme More" and "Oops!... I Did It Again."
She released a new song, "Work (Expletive)," this week. It's from her untitled eighth album, due out Dec. 3, which will include songs about her ex-fiance Jason Trawick.
"They suck," she said. "Breakups suck."
