'NSYNC, Lil' Kim To Toast Mystikal At "Secret" Party

'NSYNC, Lil' Kim, and Joe are among the artists planning to "Shake Ya Ass" during a private party in New York City on Tuesday night to celebrate the chart-topping debut of Mystikal's "Let's Get Ready" album.

As we previously reported (see "Mystikal, 98 Degrees, Shyne, Pearl Jam Assault Chart"), Mystikal moved more than 330,000 copies of "Let's Get Ready" in its first week in stores, beating out 98 Degrees' "Revelation" by more than 60,000 copies, according to SoundScan.

Jive Records, home to Mystikal, 'NSYNC, and Joe, will be hosting the event, which will also tout the rapper's appearance on the cover of the November issue of "XXL" magazine, which is on stands now.

Other artists and celebrities are expected to turn out for the Manhattan party, which a source close to the event said will have a "secret" theme loosely based on the 1999 Stanley Kubrick film, "Eyes Wide Shut," which inspired the

"Shake Ya Ass" video. Music for the party will be provided by a local artist, the Incredible DJ Touchtone.

In related Mystikal news, the rapper has just signed on to join Snoop Dogg and Bone Thugs-N-Harmony for a "Hip-Hop Halloween" concert set for St. Louis' Savvis Center on October 29.
