NEW YORK – After months of rumors and hint-dropping, pop icon Britney Spears revealed what she called her “(not-so-)secret” news — she’s 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, just in time for Las Vegas’ massive New Year’s crowds. Spears announced 16 dates, but she will perform 50 shows each in 2014 and 2015.

Spears was airlifted to a dry lake bed in the Nevada desert for the pre-dawn announcement. About 1,300 people had been bused to the remote location in the wee hours of the morning, and were waiting for her dressed in Britney Spears T-shirts or the singer’s signature schoolgirl look from her “… Baby One More Time” music video.

The Grammy-winning singer’s confirmation about the residency comes after much online speculation, including some of her own Vegas-themed tweets. 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’ helicopter hovered in the desert above her fans, who were holding giant cards that formed a 10-story-tall 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.

Singer absolves Perry of stealing

NEW YORK – Sara Bareilles says although she doesn’t think Katy Perry’s “Roar” steals from her song “Brave,” she’s enjoying her tune’s newfound success because of the chatter.

“I was stoked. I was like, ‘Great,’ ” Bareilles said in an interview Tuesday. “I was like, ‘You guys want to go get (mad) about something and buy my music, that’s great.’ “

Music fans caused a stir when Perry released “Roar” last month, claiming she stole the song’s melody from Bareilles’ “Brave,” released in April. “Roar” is currently No. 1 on the Billboard Hot 100 chart, and Bareilles’ song shot to the Top 40 after the Internet drama. “Brave” has reached gold status and so far has peaked at No. 31.
