The actor and his model girlfriend made an appearance together Saturday at the Raisa Gorbachev Foundation Gala fundraiser in London – and were practically inseparable.
"Life is great at the moment," Bloom, 31, told PEOPLE. "I've just finished a play in the West End, which I really enjoyed, and am about to start filming a new movie. It really couldn't be any better."
The sense of occasion wasn't lost on the Pirates of the Caribbean star, either. "It is amazing to come and support something associated with Mikhail Gorbachev because of what he did," the actor said of the leader's role in the bringing democracy to the Soviet Union. "He's going to go down in history because of the way he changed the world."
U2 frontman Bono made a surprise on-stage appearance at the high-rollers' charity auction, which was held in the landscaped grounds of Hampton Court Palace (the one-time home of King Henry VIII).
The Irish rocker made a speech praising the work of the Gorbachev foundation before handing the stage over to Hugh Grant, who opened the bidding on the charity auction. (It raised more than $4 million for cancer research in the U.K. and Russia.)
Grant – who was joined by fellow celebs Kevin Spacey and Kate Beckinsale – later reached deep into his pockets and pledged $250,000 for the chance to share a meal with the former Russian president.
