The Dallas star spends long periods of time away from movie producer Andrew Form, who she married in 2007, when filming the hit U.S. TV show, so they often resort to using Apple's visual calling service FaceTime.
Brewster tells People.com, "We FaceTime all of the time. We love that. There are times when I just say, 'I need to see you now.' And so we FaceTime a lot, or I surprise him and visit him or he does the same. It's super important.
"Couples shouldn't be apart for too long. We've been married for five years now and we know how important that is because otherwise you just lose touch with each other."
The actress also reveals the couple is considering children in the near future - and she is eyeing a multiple pregnancy.
Brewster adds, "My dad was a twin, so it runs in the family. Fingers crossed. We're thinking about having kids but I don't know when it'll happen. I feel very ready now."
