James Franco has sparked speculation he's dating Agyness Deyn after sharing footage of himself enjoying a drive with the supermodel.

The 127 Hours star was rumoured to be romancing the leggy beauty last year after he allegedly split from his longtime girlfriend Ahna O'Reilly, and the pair appears to be getting together .

In clips posted on his Twitter.com page, the pair can be heard chatting about Vietnamese food and Deyn's modelling jobs as they cruise the streets of Los Angeles. Franco sits in the passenger seat while the catwalk queen drives.
