Liam Hemsworth arrived on the set of Paranoia in Pennsylvania yesterday, while his fiancée, Miley Cyrus, hung near home in LA. Miley ran an errand in Beverly Hills wearing a pair of vintage Versace shades. She also took to Twitter later on to let fans know she had a "late night in the studio." She's hard at work recording her fourth studio album while Liam's back to work on his thriller. They'll eventually fit time for a wedding into their busy schedules. First, though, Liam and Miley are drafting up a prenuptial agreement that, according to reports, ensures Miley will walk with all six of their dogs, including the newest addition, Penny Lane, should they split up.
