Whoa! Kim Kardashians was killing it in a sheer Givenchy gown as we caught her doing some last-minute primping as she arrived at Sunset Tower where she was to present an award at the LA Fashion Awards.

On her arm was photographer Mert Alas and it was kept secret which award the reality star would present. Her glam squad gave a touch-up to the sexy mom's wet 'do as she got out of her chauffeured SUV.

Also on tap for the event were Fergie, Paris Jackson and Nicky Minaj -- an eclectic crowd. Paris won the Emerging Talent award; Gigi Hadid won the Best Design Debut Award for her collaboration with Tommy Hilfiger. Her mom Yolanda Won the Mother of the Year prize.

The event was co-hosted by Nick Jonas, whose brother Joe is Gigi's ex.

Other celebs included Hailey Baldwin, Lisa Rinna and her daughters Delilah and Amelia, Kristen Stewart's girlfriend Stella Maxwell and pal Lily Aldridge, and Cindy Crawford and her daughter Kaia Gerber, among others.
