Naomi Campbell refused to attend a party hosted by celebrity friend Damon Dash because it started too early.

The supermodel asked for the New York event to start later to suit her, but her demands were not met.

Dash was celebrating the launch of a showroom on 5th Avenue for the Tiret watch brand, which he owns with jeweller Daniel Lazar.

A source told The Mirror, "Naomi asked that the whole Tiret showroom launch party be rescheduled because it started too early for her. Apparently she doesn't like to go out to parties that are early in the evening. A Rolls-Royce was booked for Naomi to use for the evening, but she didn't want to come out unless it was after 10pm.

"After weeks of planning she asked that the time be changed. With so many VIPs coming arrangements could not be changed just to fit in with Naomi. It's a sophisticated reception on 5th Avenue, not an all-night rave."

Naomi's spokeswoman insisted, "The party wasn't in her diary."
