---- — NEW YORK (AP) — Britney Spears is heading to Las Vegas.
The 31-year-old pop star confirmed a two-year residency at Planet Hollywood Resort & Casino on ABC's "Good Morning America" on Tuesday. "Britney: Piece of Me" will debut Dec. 27. Spears announced 16 dates, but she'll perform 50 shows each in 2014 and 2015.
Spears was in the Nevada desert for the announcement with more than 1,000 fans. Some dressed in the singer's signature schoolgirl look from her "... Baby One More Time" music video.
The Grammy-winning singer's confirmation about the residency comes months after rumors swirled online. She said in an interview on "GMA" that the show will feature her greatest hits as well as new material.
"I'm definitely ready," she said in a taped interview, adding that she's training five hours each day.
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.
Tickets for "Britney: Piece of Me" go on sale Sept. 20. Prices range from $59 to $179.
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."
