According to FemaleFirst, the British model, who is not a big fan of Sienna Miller’s, tried to warn the 39-year-old actor, who is one of her good friends, that Miller is not the right person for him.
One of Miller’s friends who is a designer told the Daily Express, "Kate isn’t happy. Rhys was her main male friend in her close-knit group. She isn’t keen on Sienna. There is definite tension between them. Sienna was fuming after Kate gave Rhys a talking to when she heard the relationship was getting serious. Kate doesn’t think it will last and doesn’t want Rhys getting hurt."
Despite the warnings by Moss, the couple seems very happy, and they are even thinking about getting married.
The source added, "Sienna is probably the happiest I’ve ever seen her. She and Rhys are perfect together. They are having such a great time, I wouldn’t be surprised if they got engaged."
