(Cover) - EN Showbiz - George Clooney was "one of the last to leave" a star-studded party at the weekend.

The Hollywood actor attended the Vanity Fair/Bloomberg annual after-party for the White House Correspondents' Dinner on Saturday night.

Among the guests were Goldie Hawn and Kate Hudson and George made sure he enjoyed the evening.

The star was seen leaving the bash later than most - finally hanging up his party shoes at 3.45am.

"It was jam-packed, and Clooney was one of the last to leave," a spy told New York Post.

Unfortunately, the weather was not Hollywood-friendly. According to an insider, the relentless rain wreaked havoc with the stars' glamorous looks.

"It was like a monsoon," the source added. "It was raining, and a lot of ladies were walking up [to the party] with their hair falling down."

Reese Witherspoon, Charlize Theron, Daniel Radcliffe, Elizabeth Banks, Sofa Vergara, Paul Rudd and Alicia Keys were also at the A-list party.

Daniel was reportedly "particularly eager" to meet actor-and-comedian Aziz Ansari. (C) Cover Media
