Lukasz “Dr. Luke” Gottwald, a producer who’s worked with other hot singers such as Ke$ha and Katy Perry, is now working on Britney Spears’ follow-up to Circus.

“She’s an icon,” Dr. Luke said of Spears, whose new album will be “grimier” than ever. “She’s been around and always delivers, so there’s a lot for us to live up to.”

Indeed. She sets the bar high for dirtiness …

Dr. Luke, who co-produced and co-wrote the title track to Circus, says he has some new ideas in mind that will help shift the pop star’s musical style.

“It’s early in the process, but I want [the sound] to get harder in some ways,” he says “and maybe a little more deep into electronic – even grimier.”

Sounds filthy. Spears has reportedly finished three new songs for the album, and grimy new release is slated for an early 2011 release. Supposedly.

Looking forward to new music from Britney Spears? Does this shift in style sound like a good one? Sound she clean up her act instead? Discuss.
