The 20-year-old actress is bemused by how fascinated fans are by her relationship with the Whitestarr frontman. She says, "Cisco and I are dorks, that's why we work so well. "We just get on so well together. But I find it hard to work out why people seem so obsessed with us both. "It's nothing new, two people being as one, is it? "Anyway, we're both completely boring."
