Sean Penn was officially made an ambassador at large for Haiti at the Cinema for Peace benefit on Saturday night, which benefited the Oscar winner's J/P Haitian Relief Organization.

The event raised $5 million, and stars like Demi Moore, Melanie Griffith, George Clooney, Julia Roberts, Orlando Bloom, Mel Gibson, James Gandolfini and Hilary Swank attended and made generous donations.

During the fundraiser, Penn was offered the job by Haitian foreign minister Laurent Lamothe, and Penn gladly accepted, adding that it would be a nice "change being called 'Hey you [expletive]' to 'Hey Mr. Ambassador.'"

The almost-31-year-old Ryan Gosling and the 51-year-old Sean Penn are the perfect examples of the rising Hollywood superstar and the classic, iconic film actor -- and they're starring alongside each other in the upcoming Gangster Squad.

We can't wait to see how two of our favorite stars in 1940's costumes manage to keep the mafia from infiltrating LA. Kinda like a retro Bloods and Crips!

The film also stars Josh Brolin and Emma Stone. We can't wait to see her in bright red lipstick and vampy vintage dress!

Sean Penn certainly knows how to cause a bit of controversy, and we're curious to see how the media and the public will react to his latest interview.

Penn appeared on Piers Morgan Tonight and voiced his support for the Occupy Wall Street protesters, but he also chatted about everything from President Obama to the Tea Party. "You have what I call the get the 'N' word out of the White House party, the Tea Party, this kind of sensibility, which is much more of a distraction," Penn said. "At the end of the day, there's a big bubble coming out of their head saying, you know, can we just lynch him?"

The Oscar winner also spoke about his efforts to help Haiti and his recent visits to the Middle East -- click the video above to see a snippet of his interview, and click here for the full transcript.

While leaving Giorgio Baldi with new girlfriend Shannon Costello, actor Sean Penn lost his temper with photographers ... spitting at the cameras!

The hot-tempered actor has had a history with paparazzi-involved scuffles. Back in 2009, Penn kicked photographer Jordan Dawes. As a result, the actor received 36 months probation and was ordered to serve 300 hours of community service.

As for this new relationship ... Penn, 51, and Costello, 26, went public as a couple last week, and over the weekend, the duo hit the streets in Malibu for a run.

By the looks on Costello's face after Penn's spitting encounter, doesn't look like she's too impressed.

One of Hollywood's sexiest pairs has sadly ended their months-long relationship.

Scarlett Johansson and Sean Penn are officially over, according to PEOPLE.

After Penn was seen hanging out with several sexy chicks in Cannes during the film fest (ScarJo was in New Mexico, filming The Avengers) we started to suspect something was up between the pair.

They had recently gone public with their relationship, allowing photogs to capture them holding hands, as they made their way to a White House Correspondents' Dinner in Washington D.C. last April.

Scarlett and Sean were first linked back in February, after they were seen getting flirty over lunch in LA.

The star's reps have declined to comment on the split.

Sean Penn is doing his best to keep up with much younger girlfriend Scarlett Johansson, and if daily jogs keep his body tight, keep on running!

Penn, 50, is enjoying accolades for his recent film Tree of Life ... co-starring Brad Pitt. The drama screened at the Cannes Film Festival ... and both audiences and critics praised the 2 1/2 hour flick. Kudos!

Sean Penn, one of Hollywood's original bad boys, caused problems at the annual White House Correspondents Dinner over the weekend, the New York Post reports.

Penn supposedly raised eyebrows when he refused to put his hand over his heart for "The Star-Spangled Banner."

Then Penn and girlfriend Scarlett Johansson got too close for comfort at the formal dinner. A witness told the Post:

"She plopped down in his lap, and they were kissing."

Sources also said that the two left the room for an hour, after which Penn came back to their table looking disheveled.

The pair held hands as they left an afterparty in early morning hours.

See who else was at the dinner to witness the canoodling after the jump!
