Q-Tip, Heavy D, More Slated For Launch Party

Q-Tip will be one of the DJs on hand during the launch party for Onelevel.com, a new Web site described as "the one-stop shop for the hip-hop fanatic."

The high-profile launch party, which will take place Sunday, May 28 at Conscience Point in Southampton on New York's Long Island, will be hosted by rapper Heavy D.

DJ Mark Ronson will also be spinning records for a guest list that includes Leonardo DiCaprio, Def Jam executive Russell Simmons, and Bad Boy Records executive Andre Harrell.

Q-Tip, whose debut solo album "Amplified" has gone gold, recently appeared on Lucy Pearl's debut album (See "Lucy Pearl Delivers Snoop, Q-Tip On Debut").
