Oprah Winfrey Climbs Sydney Harbour Bridge

Oprah Winfrey joined the biggest ever group climb of Sydney Harbour Bridge yesterday (12.12.10).

The talk show host and her best friend Gayle King were among 250 people who scaled the famous landmark during her visit to the country, where she is taping two special shows for the final season of her talk show.

Oprah - who flew 300 viewers Down Under with her - also sailed round Sydney Harbour with Russell Crowe this morning (13.12.10) onboard a yacht named Eagle Rock, with 20 other Vessels tailing her route.

Wearing a white cap given to her by the actor, she said: "I'm having the time of my life."

The 56-year-old star had an action-packed weekend, which also saw a waterfront reception with a fireworks display thrown for her on Saturday (11.12.10), and a visit to Bondi Beach yesterday.

It has also been revealed the guests for the Australian episodes of her talk show - which will be filmed in front of 12,000 fans at Sydney Opera House - will include Russell, Nicole Kidman and her husband Keith Urban, Hugh Jackman, rapper Jay-Z and rock band Bon Jovi.

She has also confirmed the shows will end with a "soaring finale", with a performance by U2 - who are currently touring Australia - heavily rumoured.
