A battered Sixties caravan might not be top of every young girl's wish list but for Gemma Willmer it was a dream come true.

After two months of saving, the 19-year-old Robbie Williams fan finally had enough to buy the caravan, which featured in one of her idol's pop videos.

The supermarket worker from Thakeham, near Storrington, is such a devotee of the former Take That singer she has been to every one of his British concerts this year.

Every inch of her bedroom is covered in posters and pictures of Robbie and she was happy to pay hundreds of pounds for the caravan.

The Safari caravan featured in the video for Robbie's 2000 hit Supreme, in which the star played the part of a racing driver competing against Sir Jackie Stewart.

In the video, original footage of the famous racing driver in the Sixties was put together with footage of Robbie to tell the tale of the rise and fall of a would-be champ.

During the video, the singer is seen sitting in the two-berth caravan and on its steps. He even slept in the bed.

At the end the caravan door jams, trapping Robbie inside and making him miss the race which could have resurrected his flagging racing career.

Brighton-based classic car dealer Gerry Wadnum, who owned the caravan, decided to advertise it for sale after the shoot.

He put up a notice at the Goodwood Revival Meeting where it was spotted by Gemma's mother, Lynne, who immediately realised how much it would mean to her daughter.

Gemma, who paid £695 for the caravan, said: "When she came home and told me I thought she was having me on. We came to have a look to make sure it really was the right one and I decided I had to have it.

"I am so excited because I am a big fan. My friend Theresa Collins and I must be the biggest fans in Britain. I just think he's dead good.

"I have been to 13 concerts this year and 11 last year. There was one time last year when Theresa and I went to a concert in Exeter where we stood in a field for hours in the freezing cold.

"We went to bed at about 2am, got up at 7am, got the train back to Brighton where we stood outside the Brighton Centre for five hours to get in to see exactly the same show."

Her bedroom is crammed with more than 40 Robbie Williams T-shirts, jackets, sweaters, hats, bags, key rings and more than 60 CDs.
