Tongue-tied! Gwyneth Paltrow had a VIP visitor in her backyard on Thursday, Oct. 9  President Obama! And the Goop founder was so overwhelmed by her guest's good looks that she struggled to give a speech.

The Oscar-winning actress hosted a Democratic National Committee fundraiser in her backyard, welcoming the President and around 200 others (including Julia Roberts and Bradley Whitford) into the garden of her lavish Los Angeles home for a cocktail reception.

But when it came to addressing her guests, and in particular the President of the United States, an overwhelmed Paltrow, 42, found herself lost for words.

The mom-of two told Obama, "I am one of your biggest fans, if not the biggest," before praising him for being an "incredible role model."

She went on to talk about the importance of sustainable energy sources, and to praise Obama's support for equal pay which Paltrow (who Forbes estimates earns an amazing $19 million a year) said was, "very important to me as a working mother."

Then, overcome with nerves, the actress stumbled a little before passing the microphone off to the President, telling him flirtatiously, "You're so handsome that I can't speak properly.”

The world leader thanked his hostess and her kids Apple, 10, and Moses, 8, for "letting us crash your house," and then went on to use Paltrow's children as an example of why the world must help solve the Ebola crisis in Africa.

"I want to assure everybody that the likelihood of an epidemic here in the United States is extraordinarily small," the President said. "But there's a humanitarian crisis that's happening right now in West Africa where children not much older, and in some cases younger than Apple and Moses, are dying on the streets alone."

This is the second fundraiser Paltrow has hosted for Obama. She hosted ex-pat Democratic supporters in her London home during Obama’s 2012 re-election campaign. The President wasn’t present at that event. “I wanted to go,” he explained last night, “but they said there are no voters that I can knock on doors in London.”

After the backyard reception, Paltrow hosted an exclusive dinner for the President and 50 supporters, attended by Roberts and Whitford. Tickets cost up to $32,000.
