The Hollywood heartthrob enjoyed an evening with an array of gorgeous girls including actresses Helena Bonham Carter, Thandie Newton and Natascha McElhone, supermodel Elle Macpherson and socialite Jemima Khan, at London's plush L'Atalier de Joel Robuchon restaurant.
The event was held by Harper's Bazaar magazine and hosted by editor Lucy Yeomans.
The dinner also attracted a number of Clooney's movie colleagues, including his 'Ocean's Eleven' co-star Matt Damon and Bonham Carter's director husband Tim Burton.
British TV presenter Mariella Frostrup, who was once romantically linked to Clooney, was also among the guests.
Clooney's current girlfriend former cocktail waitress Sarah Larson was not present at the dinner.
Meanwhile, Clooney - who is in London ahead of the premiere of his new movie 'Leatherheads' tonight (08.04.08) - has warned his fellow stars not to google themselves on the internet.
He said: "A few years ago I went to check out this website that someone had talked about. There's like, a thousand people sitting in dark rooms trashing you. Brutal! You're like, 'Wow, dude!'
"I remember getting off the machine and thinking, 'Never, ever again'. I'd rather live in my own happy, quiet world where I think everyone is nice."
Pierce Brosnan is 'outrageously' kissable! Legendry actor Pierce Brosnan may not be attached to the 'James Bond' film series anymore, but he is still considered to be one of the most kissable men in Hollywood.
