Wales' only Miss World has been persuaded to return home next month to judge Miss Wales 2004.
Miss Wales 1974, Helen Morgan, is to judge this year's competition
Helen Morgan - Miss Wales 1974 - held the Miss World crown in the same year for just four days.
She resigned after it emerged that she had a young son, which was and still is against the rules. She was also cited in a divorce case.
Organisers of this year's Miss Wales launched a campaign to find Morgan to mark the 30th anniversary of her win.
They discovered the 1974 winner - the last British woman to take the ultimate glamour crown - is now living with her husband and young family in Marbella, in Spain.
"A friend of Helen's mother who has now died saw the letter we had published in a Vale of Glamorgan newspaper.
"She got in touch with Helen and we are absolutely delighted with the outcome and that she will be returning to Wales for the event."
Twenty four young hopefuls are taking part in this year's competition in a Swansea nightclub on 9 September, bidding to take over the title currently held by 21-year-old student, Imogen Thomas from Llanelli.
The winner's prize will include a month long trip to China later this year to vie for the Miss World title.
"It is a real pleasure to come home to Wales to mark the 30th anniversary," said Morgan, who is now Helen Lamb.
"No doubt being part of this year's competition will bring back many memories for me."
The former bank clerk was 22 when she picked up the Miss World title in November 1974 after being crowned Miss Wales and then Miss UK.
But her joy was short lived, as was her guaranteed £10,000 income when it emerged that she had an 18-month-old son being looked after by her mother back home in Barry.
Then a woman threatened to name her in a divorce action, which was later dropped, and she decided to step down.
The runner-up, Miss South Africa, took the title instead.
Memories of that momentous year are bound to come flooding back for Morgan when she takes her seat on the judging panel for the 2004 contest.
"Ultimately our aim is to bring the Miss World crown back to Wales," said the competition sponsor Harryono Judodihardjo.
"There is only one Welsh woman who knows how to do that, and that's Helen Morgan, so we are thrilled she's going to be involved."
