Rumors that Miley Cyrus and Liam Hemsworth have split were only further fueled after the 20-year-old singer was spotted partying with a "mystery man."
X17Online's photographers snapped photos of Cyrus and her male friend who first drove to her house in his own car, and then took the wheel of the singer's Porsche Cayenne and drove her to a friend's party.
Though Cyrus has denied calling off her wedding to Hemsworth, the former Disney star was spotted sans engagement ring on Wednesday night.
Insiders say things between the couple are complicated, and a source close to Cyrus told People magazine that Cyrus "still wants to get married," but the couple have had some big problems that they are currently working through.
UPDATE: A source confirmed to Us Weekly that Cyrus' mystery man is Hemsworth's friend Paul Khoury.
