Lewis Hamilton has admitted he rarely speaks to his father Anthony, who he split with as manager in March.
The pair were inseparable in the early stages of Hamilton’s career, but they decided to end their personal relationship due to Lewis’s "growing maturity" and Anthony’s business interests.
Up until the season-opening Bahrain Grand Prix, Anthony had attended every single race of Lewis’s career, but now the 2008 world champion admits he can’t remember the last time the two spoke.
“I don't remember the last time I spoke with him, but it hasn't been for a couple of weeks," said the McLaren driver. "We might exchange a message every now and then but we don't have too much to discuss at the moment.
"I don't think there is any friction but it's not all smiles and happiness. It's a big change, so it affects all of us.”
Hamilton is still awaiting his first win in 2010 and finished runner up to team mate Jenson Button in yesterday’s Chinese Grand Prix.
