Las Vegas- Shocking photos of a Miss USA contestant have come hot on the fashionable heels of a scandal that rocked reigning Miss USA Tara Conner.

The raunchy pics show Katie Rees, Miss Nevada 2007, exposing her breasts, passionately kissing other young women, and simulating oral sex with females and a male.

On Tuesday, Miss USA co-owner Donald Trump announced that hard-partying Conner – accused of underage drinking, drug use and promiscuous behaviour – was going to enter rehab but will keep her title.
