We have never doubted that Kim Kardashian is the queen of cleavage, even some men cannot stop but look at her from behind.

Ahh…We caught Usher staring at Kim at red carpet of the MTV Video Music Awards, while Kim was posing for the paparazzi’s cameras, Usher was busy checking her out.

She had rocked a revealing plunging Balmain ensemble, and Usher couldn’t help himself.
