Nick Lachey, Grandmaster Flash, Jared Leto and Britney Spears are the eclectic celebrities counting down the end of the year (06) at Las Vegas' Pure nightclub. Actor Leto and rap legend Grandmaster Flash are the odd couple hosting the club's second anniversary party on 29 December (06), Lachey will perform and host a Saturday night party on 30 December (06) and Spears will ring in the New Year at Pure on 31 December (06). But the evenings come at a price - revellers who want to spend New Year's Eve with Spears, drinking champagne and watching fireworks, will have to pay $200 (GBP102) for the privilege.
