Michelle Williams and Ryan Gosling keep mum on romance rumours

New York: `Blue Valentine` co-star Michelle Williams and Ryan Gosling have refused to confirm or deny their rumoured romance.

The actors who have shared some intense sex scenes in the film which is tipped for some Oscar nods, acted coy when asked whether or not they are dating, during an interview with ABC News Nightline. The 30-year-olds refused to answer and Gosling began to whistle pretending he didn`t hear the question while grinning at the `Brokeback Mountain` actress. The `Notebook` star then put his arm around the blonde actress and took it upon himself to shake her head side-to-side to indicate a `no` answer. After witnessing their odd behaviour, the interviewer said, "I don`t believe that". Gosling then responded with a joke, "I always look like I`m lying. It`s just, that`s my face". PTI
