"Twilight Saga" darling Kristen Stewart rocked the Robsten world when she issued a public apology Wednesday for a "momentary indiscretion" with Rupert Sanders, the married director of her recent film "Snow White and the Huntsman." Stewart, who has been dating her "Twilight" costar Robert Pattinson for years, apparently had a "marathon makeout session" with Sanders, who is married to Liberty Ross. She did not deny the affair and instead issued the prompt apology, which was followed by an apology from Sanders saying that he was "utterly distraught about the pain" he caused his family."

Being rich and famous doesn't make dating and love any easier. Love triangle scandals have trailed many a star, and the Robsten incident highlights how infidelity can forever shadow a celebrity. More details are just one click away, evidence that Stewart's drama isn't exactly atypical.
