I don't think he's talking to Clara, because one minute he's looking at the railings of the TARDIS, then the console, then somewhere else in the TARDIS, so unless Clara can teleport, I think it was just a fourth wall break.

Also, the Doctor at one point says "This didn't happen by the way," implying it is just a fourth wall break as this would make no sense to say to Clara.
