SOME like it hot, but the team behind Australia's biggest caffeine festival also like their coffee shaped like Marilyn Monroe.

As thousands sipped lattes at The Rocks Aroma Festival yesterday, a small team tried to break the Guinness World Record.

Over four hours, a team of 12 filled 5200 cups with 680 litres of milk and 780 litres of coffee to varying levels to make the world's largest coffee mosaic of the screen siren at the Overseas Passenger Terminal Forecourt.

"It was such a great feeling," Sydney Harbour Foreshore Authority's Head of Design Michael Donohue said. "It took about three to four months to plan and the reaction from the crowd was really exciting."

Mr Donohue said the blonde bombshell was a natural choice after their 2009 record-breaking Mona Lisa montage.

More than 115,000 people turned out for the festival.
