Jane McDonald

(3 p.m. BST) -- Channel 5 has confirmed Holland America Line and Silversea for the fourth series of Cruising with Jane McDonald, which airs next month.

The four-part series, which starts on June 8th at 9 p.m., will have a slightly different format from the previous three series -- featuring two lines for two episodes each, across four episodes, rather than a line per episode.

In the first two episodes, Jane -- who won a BAFTA for the series last month -- circumnavigates New Zealand and visits Australia on HAL's Noordam on a 16-night cruise.

Carly Perkins, marketing director at Holland America Line, said: "Holland America Line was delighted to host Jane McDonald and the Channel 5 film crew for a second time to showcase our classic style and enriching journeys, this time cruising from Sydney to Tasmania and around the highlights of New Zealand on the beautiful Noordam. We're all looking forward to watching Jane's experiences down under on TV."

Jane also visits South America on a two-week cruise on Silver Muse, starting in Valparaiso, Chile, before making her way around the bottom of the continent to the Falkland Islands.

Along the way, she stops in at various Chilean ports, sees glaciers and icebergs and visits Punta Arenas, the Southernmost city in Patagonian Chile.

Erin Johnson, marketing director at Silversea, said: "We are extremely excited that Jane chose to embark upon her South American adventure with Silversea, and specially the beautiful Silver Muse. As a Silversea guest in her own right, Jane had a wonderful experience with highlights including an intimate lunch with a local Chilean family in Punta Arenas, plus a very special visit to the glacier in San Rafael. The guests loved having her onboard, and we are very much looking forward to the programme airing."

The third series of Cruising with Jane McDonald, which aired in February, was the most successful yet for Channel 5.

The four-episode show averaged 2.2 million viewers and took a 9.4 per cent share of the total UK viewing audience during its four-week run.
