The rumour mill is rumbling on Friday with the news Kimi Raikkonen made a visit to F1 team Williams' Oxfordshire factory.
The sport10.at (Austria) and plaza.fi (Finland) websites said the famous British team had confirmed the 2007 world champion was given a tour.
Reports said it was Adam Parr who showed world rally driver and former Sauber, McLaren and Ferrari driver Raikkonen, 31, around the Grove facility.
The Finnish broadcaster MTV3 also reported the news and said Williams had confirmed Raikkonen's visit indeed took place last week.
The reports said Raikkonen's visit was for "personal reasons", but speculation that he might one day return to formula one has been circulating ever since he left the sport at the end of 2009.
Williams' Pastor Maldonado is regarded as having a solid seat but the Venezuelan rookie's teammate Rubens Barrichello is still seeking a deal for 2012.
"We are talking day by day so we just need to see," Brazilian veteran Barrichello told The Sun newspaper at Monza.
"I wish we had done a deal already but it's taking a little longer. The team is taking everything into account and they know what I can offer," he said.
