The 20-year-old model said she doesn't normally get overcome with nerves when she meets other famous people but couldn't help but be gripped by shyness when she came face-to-face with the US leader at the annual White House Correspondents' Dinner, reported People magazine.
Asked if she gets starstruck, she said, "Never. That was like my first time, ever."
The president was more interested in Kendall's half sister Kim Kardashian West and brother-in-law Kanye West, who he has met several times.
