Jude Law doesn't regret cheating on Sienna Miller.

The "Cold Mountain" actor - who had an affair with his children's nanny, Daisy Wright, in 2005 while he was engaged to the "Factory Girl" star - says he needed to accept what he had done in order to move on with his life.

He said, "There's no regret, you can't regret. I mean, I've felt regret but I've also refused to allow regret to sow a seed and live in me because I don't believe it. You feel it, it's like guilt, it's like jealousy, it's like all those horrible things and. you've just got to snip them and get them out, because they're no good. Because if you regret, in a way, have you learnt and moved on?"

Jude - who has three children, Rafferty, 11, Iris, seven, and five-year-oldRudy, with his ex-wife Sadie Frost - is glad the affair was made public because it helped him to learn from his mistakes.

The "Sleuth" star, who is currently single, is adamant he will not make the same errors in the future.

He said, "It all came out and I didn't try to defend myself, I took it on the chin. I was an idiot. I made mistakes - who hasn't? I also like to think that because of the scale on which I had to then admit to them, I learnt my lesson and I'm not going to f***ing do it again. I don't ever want to experience that pain, that upset, that confusion, that humiliation ever again."
