A spokesperson for teenage superstar Miley Cyrus has brushed off hearsays indicating the underage actress has slept with her fashion model fellow Justin Gaston, taking a firm stand she honors her mother's "hard-and-fast" rules. Reportedly according to the New York City Post's Page Six, Cyrus and Gaston "were completely all over one another offstage" at the fashion show, and the 20-year-old blew out kisses and winked at her every time he went by her on the catwalk. An informant states to the publication Cyrus was overheard revealing to a acquaintance that "she was most likely remaining at Justin's this night and that they were not going to go to the after-party and instead have a party of their own." Only the singer/actress' representative has abnegated any unlawful doings happened that night, stating: "Miley had an outstanding time at the appearance, just the whole sleeping-over affair never came about. Miley headed home with her mother and manager. Leticia is really stern with her.
