Katy Perry

Their internationally recognized names sell music and movie tickets. They promote perfumes and presidents. But when it comes to selling their own houses, celebrities often find that their cachet doesn't pull in the cash. Actors Goldie Hawn and Kurt Russell haven't found a buyer for their Malibu beach house, which comes with a raft of celeb-friendly amenities including a covered outdoor living room, a spa-like bath retreat and a meditation room. So the couple have nipped $3.5 million from last year's price, listing the Balinese-influenced oceanfront spread at $11.2 million.

Katy Perry's upcoming 3-D documentary may be titled "Part of Me," but the pop singer said it would "show everything" about her life, including her breakup six months ago with former husband Russell Brand. "Sometimes people think that we're perfect, and we know we're not perfect at all," Perry said Tuesday. "And I think it's important to start breaking down the idea that to achieve your dream you have to always be perfect or flawless or live in kind of like some fantasy world."

MUSIC To judge Katy Perry as inauthentic or unoriginal would be wrong; as with a great ad campaign, familiarity is her greatest achievement. She can feign a rocker's stance on the Alanis-inspired "Circle the Drain" or a hip-hop diva's stutter on the Rihanna-influenced "E.T. " and convince you it fits her perfectly.

Katy Perry and Russell Brand split just months ago, but now there's somebody else ... and somebody else ... and somebody else. There have been rumors of something "serious" -- but a better word might be snuggly.  Perry, for instance, reportedly got snuggly at Coachella over the weekend, sharing a little PDA with Robert Ackroyd, guitarist for Florence + the Machine. Oh look, it's another handsome British performer. There's photographic evidence of the pair holding hands and hugging, and of Ackroyd bending Perry back for what looks to be one heck of a smooch, during the twosome's second weekend in a row at the desert music festival.

Halfway through her brief 50-minute set Monday at Hollywood's Hotel Café, Katy Perry apologized for her subdued stage presence -- "I'm really sick right now," she wheezed -- and told the capacity crowd that she hoped they'd be at the Wiltern on Jan. 31 for the local date of her first headlining tour. "There will be so many amazing things to see," Perry promised.

Dr. Luke has lived in Los Angeles since 2008 but he still hasn't gotten the hang of valet parking. On a recent Thursday afternoon, the attendants at the Polo Lounge in Beverly Hills are having trouble matching the songwriter-producer's ticket to his Prius. Turns out he took his car keys with him into the restaurant — and not for the first time, either. "I grew up in New York," he explains a little later. "I never had to learn this stuff. " What Luke has learned — indeed, what he's more or less mastered — is the art of the hit: Born Lukasz Gottwald in 1973, he's the knob-turning, button-pushing, party-starting pop savant behind what seems like every second song on the radio right now. Katy Perry's " California Gurls"?

Lady Gaga, Mother Monster, social media genius. Whatever you want to call her, the 25-year-old pop star, nee Stefani Germonatta, is the first person to collect more than 20 million followers on Twitter. For comparison's sake, Barack Obama, our nation's president, has 12.8 million followers. Hmmm. Gaga has been the reigning queen of Twitter since August 2010, when she surpassed Britney Spears, the former record holder by getting 5.6 million followers. Oh how times have changed.

The 54th Grammy Awards had plenty of head-turning moments. It was impossible to ignore Nicki Minaj's red nun's habit or Fergie's orange see-through gown. But in general the traditional style hallmarks that have come to define Grammy fashion (think black, metallic, body-conscious and flashes of strong color) were pulled together in a manner that was somehow elevated and elegant. Call it refined wackiness. Katy Perry perfectly exemplified the evening's overall fashion vibe, incorporating her love for bold color and whimsical details yet retaining a conservative silhouette.

If the fashion that appeared on the Grammy red carpet seemed relatively tame, a handful of artists made up for it when they performed onstage during the awards ceremony. Lady Gaga led the pack with her arrival in a Hussein Chalayan-designed pod that was carried in the manner of an ancient Egyptian litter. She "hatched" from the egg-like structure wearing a transparent yellow raincoat-style jacket and a wide brim hat, and her cropped top and long skirt with a high slit allowed her to successfully sing and dance after she emerged.

The 2011 MTV Video Music Awards ceremony went without a host or much sense of direction Sunday night at Nokia Theatre, as a heartfelt tribute to singer Amy Winehouse and a career-rehab performance from Chris Brown offered strong moments over the course of a wildly inconsistent evening. In the salute to Winehouse, who died last month at 27, British comedian Russell Brand recalled first hearing her "raw, from-the-guts-of-humanity voice" in London before he knew who she was. "She suffered from alcoholism and drug addiction.

When Katy Perry first came on the scene, some dismissed her as a one-hit wonder. Three years later, she has proved she's a multi-hit wonder, becoming the first woman to score five No. 1 songs from one album on the Billboard Hot 100 chart. Her "Last Friday Night (T.G.I.F.)" set the precedent: It's the latest No. 1 from her platinum album "Teenage Dream. " Only Michael Jackson had five No. 1s from one album ("Bad") before Perry. But Jackson spent a total of seven weeks at the top with his "Bad" songs; Perry has been at the top perch now for a cumulative 18 weeks.
