In their own words: In a 2006 interview with TV Guide, Chris explained what it's like to date his onscreen sister: "Yeah, we've pretty much gotten used to the response of, 'Ew, that's weird. That's creepy.' The people who know us are happy, and probably expected it to happen eventually. But yeah, every once in a while we get that one person that's like, 'That's really creepy. You just kissed your sister.'"
