Singer-actress Miley Cyrus has denied reports that she is dating teen pop star Justin Bieber after they were spotted together at a party.
The former Hannah Montana star said that the dating rumours are false because she is already engaged to actor Liam Hemsworth, reported TMZ.
Asked whether Cyrus, 20, and Bieber, 19, are more than friends after they were seen flirting with each other, the actress said, "I'm engaged. That is impossible."
The pair have been friends for years, but their late night rendezvous comes just hours after Bieber's distinctive leopard-spotted Audi was seen pulling out of Cyrus' Los Angeles mansion's driveway.
The duo are also rumoured to be planning a musical collaboration together.
