Washington, May 2 : Democratic Presidential hopeful Barrack Obama did not miss out on giving his share of tongue in cheek humour on the David Letterman Show by targeting 'The Hills' stars, Heidi Montag and Lauren Conrad, both of whom are openly endorsing the Republicans.
While Heidi Montag is all support for John McCain, Lauren Conrad seems to be turning her loyalties towards Republicans and it seems that Obama has taken a clear jive into their Hills feud.
Obama targeted the duo while revealing his Top Ten "Surprising Facts" about himself for the Late Show with David Letterman, to be aired on May 2.
"My first act as President will be to stop the fighting between Lauren and Heidi on The Hills," Usmagazine.com quoted him, as saying while he read his top ten.
He further joked: "Number 5: I have canceled all my appearances the day the Sex and the City movie opens."
"Number 2: This has nothing to do with the Top Ten, but what the heck is up with Paula Abdul?"
And his topmost surprising fact actually took everyone by surprise.
"Number 1: I have not slept since October," he said.
