A week after the damaging 'Twittergate' affair, pundit Eddie Jordan thinks the 2008 world champion is set for a shock switch to Mercedes.
But when asked about the German squad at Monza and the possible benefits of joining in 2013, 27-year-old Hamilton answered: "I've no idea. I've not really thought about it.
"I drive for McLaren," he added.
Asked if he has anything else to say about the rumours, Hamilton said: "Not really."
Hamilton was also coy when asked about the Twitter affair, in which his teammate Jenson Button admitted to being "disappointed" about the release of secret team telemetry.
"Nothing happened, the head of the PR department asked me to take it off, so I did," Hamilton said. "I've moved on.
"I haven't spoken to Jenson about it and don't plan to."
