Widespread reports after the Canadian Grand Prix said the 26-year-old met with Red Bull's Christian Horner at the Circuit Gilles Villeneuve after qualifying.
"He was also spotted doing the same with Ferrari boss Stefano Domenicali," read a report in the British newspaper The Mirror.
Hamilton is being managed by Simon Fuller's XIX Entertainment and a spokesman on Tuesday denied the rumours.
It is believed Hamilton personally sought out the Red Bull talks, walking into the team's circuit offices and asking a member of the catering staff if he knew where Horner was.
That meeting preceded Hamilton's latest controversies when he got involved in more collisions in Montreal.
"He seems to be in a bit of a difficult situation," Horner is quoted by the German newspaper Welt, whose own headline referred to the Briton as 'Rambo'.
I think he's trying a bit too hard. Maybe he just needs a bit of time out
"I think he's trying a bit too hard. Maybe he just needs a bit of time out," added Horner.
"Maybe (it) is something he needs after literally growing up at McLaren over the last decade -- drop the emotional baggage which inevitably grows in every relationship," he wrote in his Telegraph column.
