London, February 5 : Tilda Swinton has dubbed her threesome with the father of her kids and her lover as `the best thing for the children.'

The Oscar-Winning actress, who has a live-in relationship with painter John Byrne, aged 68, and artist-partner Sandro Kopp, aged 30, insisted the `healthy' arrangement helped both her and her 11-year-old twins.

"It''s not something I try to promote as a radical lifestyle choice," the Daily Express quoted her as saying.
