He is said to have "changed the world" and has even won a Nobel Peace Prize.
But even Mikhail Gorbachev is not immune to the charms of A-list beauties, and he looked delighted at the chance to plant a kiss on Sharon Stone's cheek.
The screen siren was co-host of the glitzy charity gala in honour of the last Soviet leader's 80th birthday at the Royal Albert Hall, along with Kevin Spacey.
And black-tie was the theme of the night, showbiz beauties such as Katherine Jenkins and Goldie Hawn dressed to the nines in designer gowns.
Fifty-three-year-old Sharon was radiant in a blush pink floor-length Christian Dior gown.
Meanwhile, Welsh singer Katherine, who performed, looked stunning in a body-con lavender dress.
Mel C, Shirley Bassey and the London Symphony Orchestra also took to the stage.
Meanwhile, lending their star power as well were Milla Jovovich and Arnold Schwarzenegger.
Mr. Gorbachev, who actually reached the milestone birthday on March 2, arrived with daughter Irina Virganskaya on his arm.
The A-list affair raised millions of pounds for various charities including the Raisa Foundation, named in honour of Mikhail's late wife, who died in 1999.
