Meryl Streep says the only person she has been star-struck by is President Barack Obama.
The 60-year-old actress can usually maintain her composure when she meets other actors she respects but admits she was in awe of Obama - America's first black President - and his wife, First Lady Michelle Obama.
She said: "I went to the Whitehouse and was star-struck by our President and First Lady. Although I was also impressed by Bruce Springsteen, who was there as well."
Streep - who can currently be seen in new romantic comedy 'It's Complicated' opposite Alec Baldwin - is fully behind President Obama and believes he is more than capable of making the right political choices for the US.
She added: "I think it's thrilling to have someone who is thoughtful and can articulate, with a certain amount of passion and dispassion, the necessary choices that we have in the world."
