And with a mystery man on top of that!!!
Miley was already seen out with another man the same night fiance(?) Liam Hemsworth was spotted with January Jones, but if there was any hope of that being a one-time thing, we're sorry to burst your bubble!
Gurl went out with a non-Liam hunk again on Thursday night! Apparently he drove to the studio where she was working in his own car, but then he took the wheel of hers when it was time to party-pop in NoHo. We hear they left a house party together after a few hours of wine-drinking.
