Miley Cyrus and Kellan Lutz partied together at the opening of Beacher's Madhouse at MGM Grand Hotel & Casino in Las Vegas on Friday (Dec. 27). The two spent the night drinking, dancing and fueling rumors that they might be dating. Reports of their rumored romance first surfaced after they were spotted arriving in Miami on the same private jet on Dec. 18.
There are some conflicting reports about how much time the 21-year-old singer and 28-year-old actor spent together at the event. The Daily Mail claims Cyrus "[made] her romance official" ... but also cited her grinding with two other men.
