And it appears Brawn GP's bosses weren't at all happy with Button's McLaren visit.
According to the Daily Express 'Button's relationship with Brawn broke down so badly that they removed an offer that could have been worth £12million next year before he signed for McLaren.
'Just a month after being lifted to the heights of World Champion by his team, Button was left in no doubt that he had let them down in a phone call with team principal Ross Brawn at the weekend.
'That came after a breach of contract when Button was shown around the McLaren factory, a move which shocked Brawn, who thought he was still in the middle of negotiations with Button.'
The phone call with Brawn resulted in both parties feeling wronged and the offer of an £8m per year salary plus up to £4m in points bonuses being taken off the table.
Two days later McLaren announced they had bagged the reigning World Champ for just £6m a year.
