Kate Beckinsale "knew within five minutes of kissing" her husband she would marry him.
The 'Snow Angels' actress - who met her director spouse Len Wiseman on the set of their movie 'Underworld - initially tried to deny her attraction to Len because she was dating her 'Underworld' co-star Michael Sheen at the time.
She said: "It was one of those things that was happening but that we tried to pretend was not happening for a long time. Len and I were both with other people at the time, and the whole thing was really difficult.
"We made the film, and it wasn't until after it had finished that it finally dawned on me how much I liked him. I knew within five minutes of kissing Len that I would marry him."
Kate - who has a nine-year-old daughter Lily from her relationship with Michael - is thankful Len and Michael get on well, because it makes life easier for her and Lily.
She added: "Len and Michael got along very well before Len and I got together because they already had a good working relationship, and they both liked each other anyway."
