“I’m already working on my new record,” Paris . “I’ve been in meetings with Scott [Storch] and we’ve been working on it.”

“I’ve been working on it with Scott for a few weeks,” the heiress adds.

“She takes voice lessons several times a week,” says an insider. “She’s really serious about her music career.”

“Of all her projects, her music is the most important to her,” says a source close to Hilton. “She really works very hard to be taken seriously in the industry and make good music people will enjoy.”

Pop and hip-hop producer Scott Storch is reportedly peeved that none of his A-list lady friends, like Paris Hilton, Lindsay Lohan, Kelly Rowland, or Britney Spears, bothered to show up at his birthday party at Miami’s Mansion Nightclub last month.

“Kelly Rowland was supposed to come and sing a special ‘Happy Birthday’ to him and she was a no-show, too,” a source at Page Six reports.

Reps for Scott say “quite the contrary.” “Scott was not upset at all – he had Derek Jeter and Ludacris there, and a naked girl even popped out of the cake.”
