Kendall Jenner made a surprise appearance at the Tony Awards on Sunday at the Radio City Hall in New York City in a peach-colored Calvin Klein sequined dress. Jenner turned heads as she walked down the red carpet with her date for the evening -- Francisco Costa, Calvin Klein's creative director, and the designer of her dress.

The 19-year-old model made a show-stopping appearance at the award ceremony, with a high neckline and long sleeves. The outfit also had a keyhole cut-out at the back. Jenner let her locks loose with a center parting and light waves, E! Online reported. She paired the outfit with satin stilettos and a silver box clutch.

Along with Jenner, Bella Hadid, the daughter of “Real Housewives” star Yolanda Foster, also made a surprise appearance at the award show, wearing a strapless black-and-white silk gown by New York-based designer Prabal Gurung, Daily Mail reported. Hadid also walked the red carpet with Gurung, marking another model-designer pair at the ceremony.

Ashley Greene, the actress playing Alice Cullen in the renowned "Twilight" movies, made an appearance at the show with designer date Jason Wu. She wore a shimmering olive green dress.

Model Vanessa Axente was also seen walking the Tony Awards' carpet in a red frock, hand in hand with designer Joseph Altuzarra.
