The 32-year-old sportsman, who is living in Los Angeles where he plays club football with LA Galaxy, said that he likes it when his kids use a British accent but now that they are picking up American accent as well, he is not happy.
"They sound as if they are from London - and that is how I want them to sound - but they are getting little parts of an American accent," Mirror quoted Beckham, as saying.
"Romeo keeps saying 'Awesome' a lot, 'Awesome, awesome'," he added.
The England star, who was being interviewed on ITV's 'This Morning,' was also asked about his underwear.
"Used to be boxers, but now it is Y-fronts," Beckham said.
