And since Fiennes (who did not get to see his Constant Gardener co-star Rachel Weisz win her Oscar this week because he is appearing on stage in Dublin) and Annis recently split after he was allegedly again unfaithful, I expect Kingston, 42, to exude triumphalism, or at least smugness. "I know nothing about it, other than that I'm told they are no longer together," she says coolly, as we sit in a south London cafe, her features free of make-up and her auburn corkscrew mane tamed into a ponytail. It's been so long, I can't quite believe I was ever married to him." After their split, she called him the love of her life, said she couldn't bear to watch his performances, and had to flee London because of the memories of her life with him. I think it's a little unfair that he's held up and scrutinised in this way when I'm sure that if you sat on a bus or a Tube, 20 per cent of the passengers would have done similar things." I tell her she seems much stronger than in the past, but she thinks this is due to the tough roles we have seen her in: Moll Flanders, ER's Dr Corday, Boudicca, the duplicitous femme fatale of Mike Hodges's Croupier. "Oh God, you're gonna make that the headline, aren't you? "Well, I do feel that having gone through labour - 36 hours, no epidural - I can go through anything," she concedes.
Last week, Kingston flew into London to slip confidently into a new role as Christian Slater's co-star, playing the cruelly domineering Nurse Ratched in the West End revival of One Flew Over the Cuckoo's Nest. And maybe my second marriage." And although she still doesn't mention Fiennes by name, she now has a laid-back, LA attitude to his "commitment issues", past and present.
The abandoned wife who nearly cut her wrists now has seven starry seasons in ER, a healthy film career, an adoring second husband (German journalist Florian Haertel) and an adored daughter, Salome, five, to bolster her self-esteem. I actually went to see The Constant Gardener - the first time I have seen him on film since we split up - and I was able to sit through it and really enjoy the movie, just thinking, 'Oh, there's a fantastic actor on screen.' But there was no other reaction whatever. "There are so many actors in Hollywood who go through so many relationships, and are allowed to, that I think he should be left alone to live how he chooses, without being under the glare of the media.
In LA she stayed with Alfred Molina and Jill Gascoigne, won the part of Elizabeth Corday in ER (the producers had admired her gutsy performance as Moll Flanders) and got chummy with cast members Julianne Margulies, Anthony Edwards and George Clooney, who taught her how to play basketball.
But when another friend, actress Annabel Apsion, set her up on a blind date with Haertel, she was suspicious.
He is a tall and handsome guy with 44 inches chest and 32 inches waist sizes. He has a very interesting dating career as he has dated Alex Kingston, Francesca Annis, Gina Gershon, Lady Amanda Harlech, Ellen Barkin, Lisa Robertson and Patti Smith. His fan pages are available on Facebook and Instagram where more details of his characters are available.
