I don’t expect him to be at every little thing that I do, and vice versa. He’s got a lot of stuff on his plate and so do I. There’s a mutual understanding. "We would like for it [their pre-nuptial agreement] not to be a big thing, but the reality is it has to be. Because there’s things that are specifically mine, and he’s got huge friggin’ conglomerate stuff and I’m not looking to take that from him. So it has to be dealt with.Anytime you get married to somebody [it does] - and I should know. This’ll be marriage number three.
