NEW YORK – Katy Perry says although she’s “older and wiser,” she still plans to have fun.

Perry debuted 12 songs from her new album, “Prism,” to be released Oct. 22, in front of an audience of 100 industry insiders and journalists Thursday night in New York. The beat-driven album features likable, radio-friendly tracks, much like her multi-hit 2010 effort, “Teenage Dream.”

The 28-year-old pop star played songs like the ’80s-inspired “Birthday,” which she called “something like Mariah Carey would have put on her first album.” She said “Unconditionally” was her favorite song and she was proud to have written it. “Dark Horse,” which features rapper Juicy J, sounds like a Southern rap-techno mashup.

Perry’s first single, “Roar,” bumped Robin Thicke’s “Blurred Lines” from the top spot on the Billboard Hot 100 chart this week. She debuted the music video for the track Thursday.

“I’m very excited to bring visuals to a lot of the songs and play them live,” she said.

“Prism” features producers Dr. Luke, Klas Ahlund, Sia, Bloodshy, Greg Kurstin and others. Some of the new tracks include emotional lyrics. She sings “one man’s trash is another man’s treasure” on “Double Rainbow,” and on “By the Grace of God,” she sings “wasn’t going to let love take me out that way.”

“Prism” will include 13 tracks; its deluxe version will have 16 songs. The singer was excited and playful at the event, and even cracked a few jokes.

“It’s the ‘Prism’ preview. I wanted to show you what my prism can do,” she said to laughs.

Aguilera’s son helps to keep her in shape

NEW YORK – Christina Aguilera recently debuted her slimmed-down body, but the singer says she doesn’t work out like crazy.

The 32-year-old is on the cover of Maxim magazine’s October issue. She’s sporting a bra and a big shirt in the cover photo and a fitted dress in the inside spread.

In a phone interview Thursday, Aguilera said her daily routine includes working out — on some days. She said: “If I can squeeze in a workout, great. If not, that’s OK, too.”

The Grammy winner added that her 5-year-old son, Max, is also keeping her in shape: “Running around with him all day is pretty good exercise.”
