Jude Law’s ex-wife Sadie Frost has spoken out about his affair with his nanny, claiming that she knew he would cheat on Sienna oiller at some point. The actress and designer, whose divorce from Law was finalised last month, said: “I was very, very lucky that it didn’t happen to me. This is between Jude and Sienna but what I will say is that a situation like this was predictable. It’s not my problem, I just feel bad for Sienna, but she’s cool.”
