Actress Tilda Swinton has opened up about her unusual living arrangements with her longterm partner and her toyboy lover, insisting their relationships are "really very dull".
The Oscar winner has 11-year-old twins with playwright John Byrne, 68, but has been enjoying a romance with boyfriend Sandro Kopp, 18 years her junior, for the last few years.
Swinton attracted attention to her unconventional domestic life when she took Kopp along as her date to the British Academy of Film and Television Arts (BAFTA) Awards in London earlier this year (08), leaving Byrne at home in Scotland to look after the kids.
But the Michael Clayton star insists her love life is not complicated - because she and Byrne have not been "sweethearts" for four years.
And she reveals Byrne has found himself a lover, too, who sometimes stays over at the family home when Kopp is also around.
She says, "He has got a lady friend. A friendly lady! A sweetheart! I think it's a foursome now. Everybody is very close friends.
"The truth is, I tend to share my bed with two children and a dog here (in Scotland) - and it is crowded and very, very cuddly."
Swinton, 48, is adamant her relationship with Byrne and Kopp has not affected her children - instead, they live in a house full of love.
She adds, "This has been the case for the children for at least half of their lives... what they have is two parents who are really happy, and who are very much in harness.
"Very often people have children with people they are no longer sweethearts with and then have a relationship with someone new. What rarely happens is they are still good friends and continue to live in the same house.
"The thing with us is that this has been the case for four years and nobody noticed until the beginning of this year."
But Swinton is defensive of her and Byrne's relationship being described as 'open': "That sounds like anything goes and it's insulting to the relationships that are there... John and I haven't been sweethearts for a while... Our situation is very much more ordinary that the papers would like to think. We're really very dull."
