In a recent interview with MTV News, producer Rodney Jerkins said that, on her upcoming Femme Fatale album, [article id="1658923"]Britney Spears got "hands-on,"[/article] supplying him with "a lot of ideas" and helping shape the energetic sound of the project.

"She's great. She gets it," Jerkins said. "She is a top-notch veteran pro at this now."

So it should probably come as no surprise that, somewhere along the line, Blink-182 drummer Travis Barker came to be involved in recording the album -- because, while we're not sure if bringing him onboard was Britney's idea, he is most certainly the kind who can bring the energy.

And, as Jerkins said in a recent sit-down with Headline News' "Showbiz Tonight," the experience of working with Spears and Barker was a new one for everyone involved.

"I'm really excited. ... I did two songs on her album, and one of the songs I did, I brought in Travis Barker, and it's got this rock feel which is out of the box, out of my norm, and I think it's out of her norm as well," Jerkins said. "We had a great time making this record."

Jerkins didn't elaborate on much else about the Barker song or Britney's album, saying only that the project is "classic Britney spears, uptempo heavy, of course. It's new and different."

A spokesperson for Barker confirmed to MTV News that the collaboration happened "about a month ago" but, much like Jerkins, wouldn't reveal any additional details of the song. Spears' Femme Fatale is due March 29.
