Stress making Barack Obama grey-haired 'Barack Old-bama'

London, Apr 29 (ANI): Barack Obama is so much under stress since he took office in 2009 that he has now become President 'Old-bama' with grey hair.

The US President revealed the strain of office by showing off his grey hair recently.

And his salt-and-pepper look was in stark contrast to the dark locks he had when he moved into the White House just last year.

And the 48-year-old politician shocked supporters in Iowa with his silver barnet.

"It was more like Barack Old-bama than Barack Obama. I couldn't believe the change," the Sun quoted one supporter as saying.

Last year there was speculation that the President had been dyeing his hair to win over voters, but his barber denied it. (ANI)
