Patrick Schwarzenegger's sister, Christina. Yep — Miley Cyrus' BF Patrick has a 23-year-old sister who is reportedly dating Braison Cyrus, Miley's brother. As in, Miley and Patrick's siblings are dating. As in, two sets of siblings = one slightly awkward double date. After a preliminary cyber stalk, we can tell you Christina's a bit silent on social but Braison has an eye for Miley-esque Insta-weirdness, so this may work out, and 2015 may be the year of the Cyrus-Schwarzenegger takeover! Though we have to say — if we're thinking about #FiveWordsToRuinADate then "your sister's dating my brother" is pretty high up there.
