Tilda Swinton has spoken about her lovelife, which has been the subject of much speculation.

It appeared that the Michael Clayton Oscar winner had both a husband and a lover, which is true but a little different, and less alternative, than some might have thought.

The 48-year-old actress revealed that her marriage to Scots artist and playwright John Byrne ended five years ago but the couple agreed to continue living together in the home they share with their ten-year-old twins.

The limelight dodging star also said she began dating German-born artist Sandro Kopp, 30, four years ago while filming The Chronicles of Narnia in New Zealand, adding that he regularly visits her Nairn home and plays a role in her children's lives.

The Burn After Reading clearly doesn't understand what all the fuss has been about especially as all involved are happy with the arrangement.

"I've been with Sandro for four years and John and I haven't been a couple for over five. My children have known and loved Sandro for almost half their lives," she said. "Maybe the unorthodox thing, it's sad to say, is that we're all so happy and this comes as a shock to people.

"When you say you love the father of your children and you also are in love with someone else, they immediately assume you're all in bed together. The idea that you have to defend yourself seems really sad."
