Get into the groove — the newest addition to the iPod (search) family is expected to be a pink nano loaded with all of Madonna's hits.

Apple (search) plans to unveil the new vanity version of its razor-thin music player today in San Jose, Calif., according to industry insiders.

The pink music player would be the first artist-backed iPod since U2 (search) lent its name and music to a jet-black special edition last year.

Rumors about the Material Pod have been circulating on the Internet faster than the latest iTune. Gadget-watcher Jonathan Dusing even snatched up the Web address madonnaipod.com in hopes of cashing in on the craze.

"They don't have any colored iPods anymore," said Dusing, an Arizona computer technician. "I think the pink ones would do pretty well."

The new iPod is being unveiled a month after the company introduced the iPod nano (search) along with the ROKR iTunes cellphone from Motorola.

Madonna, who sang "Justify My Love," might have to justify her turnaround.

Before she started hawking the ROKR and the iPod, she was very vocal against music file-swapping, and refused to make her tunes available for legal online downloads.
