Hollywood heartthrob George Clooney will host a $6 million fundraising dinner for Barack Obama at his Los Angeles home as the president fills his campaign coffers to fight Mitt Romney. 

The event, on May 10, will incorporate in the "Dinner with Barack" campaign which the president's political braintrust dreamed up to drum up small donations and fire up grassroots adherents. 

Obama fans are invited to enter the contest and give as little as $3 greenbacks on a webpage titled "Obama, Clooney and You" featuring footage of the Oscar winning star and the president. 
Fortunate winners earn a spot at the dinner. 
"George Clooney is playing his part to help re-elect the president, but he knows that it's grassroots supporters like you who will decide this election," the internet site reads.

"That's why he'd like you to invite you to donate for a chance to play a part in this event." 
A campaign official said the A-list dinner, likely to be the most star-studded night of the Obama campaign so far, was predicted to draw 150 adherents paying a cool $40,000 each for a ticket. 
Obama and Clooney last met in March when the star of "Oceans Eleven" and "The Descendants" made a trip to the Government to brief the president on a surreptitious visit he had made to war-torn Sudan. 
Clooney also attended a state dinner for Brit P. M. David Cameron. 

The president intermittently visits California, especially Hollywood and Silicon Valley, where there is a strong base of committed, famous and made supporters to help him raise millions of bucks ahead of November's election. 
Exclusive events for the wealthy, like the one at Clooney's house, are commonly coupled with cheaper, larger and more open fundraisers with less well-heeled followers who get fired up by Obama's campaign speech. 
Obama, who is rebuilding his countrywide political machine to fight the all-but-certain Republican nominee Mitt Romney, related Monday he had raised $53 million for his reelection effort in March. 

He has now taken in over $200 million for his campaign and up till the end of February, he spent $75 million, much of it on his new grassroots substructure. 
Obama will be trying to beat his total of $745 million in the 2008 election, which also included the long and pricey Democratic first battle against his then foe and now Secretary of State Hillary Clinton.
