Lily James and Dominic West were seen kissing when they were filming The Pursuit of Love in 2020, which was a big deal because he was married to Catherine Fitzgerald and the father of four children! Dominic and Catherine made a huge show of kissing in front of the media and the press, sharing a message that said, "Our marriage is strong and we're very much still together." but this just served to further confuse the situation (and make it seem much more... strange?).
Since they are still together now, they must have been speaking the truth.
