"They are very, very happy," Sadie Frost tells PEOPLE of her good friend Moss, 34, and her rocker beau Jamie Hince.
But Frost, the ex-wife of Jude Law doesn't seem convinced by recent tabloid reports that the supermodel and Kills guitarist are planning to get hitched.
"I really have no idea," Frost said at an east London MySpace party for her new horror flick Beyond the Rave. "I don't know, people just make this stuff up anyways."
(The couple have reportedly been dating since last summer, after Moss's split from British bad boy Pete Doherty.)
Frost also said that her 11-year-old son Rafferty is already taking after his famous father. He "looks like Jude," she said – so much so, that he's playing a "young Jude" in Law's upcoming film Repossession Mambo.
Now both Frost and Law are encouraging their son's thespian ambitions, but not at the expense of his schoolwork.
"He is very interested in acting," she said. "You should encourage your kids in what they want to do. He still needs to study, but I would never hold him back. When he's out of school, he can decide whether or not he wants to go his own way."
