Leona Lewis unites the masses, even boy bands

There's no denying the gentle power of British import Leona Lewis' voice: She can bring the world together with her harmonies -- and even a former boy-bander or two.

Tuesday night, ASICS threw a bash to celebrate the release of Lewis' second studio album, "Echo," at Hyde Lounge, where fan and fellow chart-topper Justin Timberlake showed up for support.

Dressed down in a hoodie and ski cap, Timberlake (sans girlfriend Jessica Biel) devoted nearly all of his time and attention to Lewis, looking stunning in a strapless band dress with corset detail by Herve Leger. JT camped out at her private table, where the two exchanged hugs and conversation.

A pivotal moment came, however, when Timberlake and former 'N Sync band member JC Chasez collided, the first time we've seen them in public together in nearly a decade.

The pair looked as if they'd never said goodbye, chumming out with yet more hugs and conversation. Don't you love it when we all get along?
