Reality star, Kim Kardashian stepped out in grand style by dressing up like her Idol, Cher, to watch her perform in Las Vegas on Saturday night.

The 37-year-old mother of three who was out for her high school reunion with friends recreated Cher's 1974 outfit she wore for a production of The Rocky Horror Picture Show.

Kim stormed the concert with her friends who all were celebrating 20 years since graduating from Marymount High School in Bel Air.

The Keeping Up With the Kardashians star recreated the Pop legend's outfit by rocking balloon pants with a stomach-baring beaded waistline, matching black top and faux.

She also documented the whole the event with her millions of social media followers, by posting photos and videos from the concert.
