DiCaprio, Whitney Port 'not dating'

Leonardo DiCaprio has reportedly dismissed rumours that he is dating Whitney Port.

According to Us Weekly, a source close to the Shutter Island star has insisted that DiCaprio and Port are not dating.

The source said: "It's about as true as The City - it's made up! They don't know each other. They never exchanged numbers."

The 34-year-old Hollywood actor has previously dated models Gisele Bundchen and Bar Rafaeli.

Shutter Island, directed by Martin Scorsese, is scheduled for a February 2010 release.
