Clear Channel stations WHTZ (100.3 FM), WWPR (105.1 FM) and WKTU (103.5 FM) are getting together with Top Button Inc., a marketing outfit, to present "Style Stage NYC" May 5-6 at the Metropolitan Pavilion on W. 18th St.

It's a fashion expo with music. Some 60 designers will sell samples in the pavilion during three separate music sessions: 6-10 p.m. Friday with Paul, 10 a.m.-2 p.m. Saturday with Jagged Edge and 3-7 p.m. Saturday with Lachey.

This event is being held in place of Z100's traditional "Zootopia" show, the idea being to broaden its appeal and involve more stations.

Tickets are available through www.topbutton.com.

DIAMOND DAVE COUNTDOWN: David Lee Roth said yesterday he wouldn't be surprised if he's fired from his morning gig at WFNY (92.3 FM) "within the next three weeks."

Roth, who has had low ratings since he replaced Howard Stern in January, says station executives have ordered him to do "a 'traditional' morning show instead of the show I was hired to do."

The restrictions make the show "pretty boring," Roth reiterated yesterday.

When he announced the changes Friday, his open resentment seemed to extend even to disinterested readings of some commercials - which in radio as elsewhere may be the fast track to the door.

Roth's actions suggested what's really playing out now are contract issues. He reportedly signed for $4 million a year, and he said Friday, "If I don't play, I don't get paid." He raised the possibility he was being "set up," though he never made that a direct accusation.

Meanwhile, reports in several trade magazines, including Inside Radio, have suggested Roth has been difficult about more than just the on-air changes.

AROUND THE DIAL: Filmmaker turned Broadway impresario John Waters guests tomorrow with Mark Riley, 5-7 a.m., on Air America (WLIB, 1190 AM). ... Morning host Star of WWPR (105.1 FM) yesterday said Jay-Z is one of his top three all-time rappers, which was interesting because Star has often seemed to feud with him. Star also sparked a heated discussion yesterday over whether the late Roberto Clemente was black. DX21 argued that he was, because the Puerto Rico-born baseball great shared the common heritage of oppression. ... XM Satellite Radio says it has passed 6.5 million subscribers and is on track for 9 million by year's end. Sirius, fueled by Howard Stern, has been gaining ground on XM the last two quarters, and the question among radio analysts now is whether the main crest of the Stern wave has passed.
