When Catherine Zeta-Jones installed bullet-proof windows at her Swansea mansion, many assumed the Zorro star was taking Hollywood-style security measures for the protection of her family.
However, it has now been revealed that the Welsh beauty and her famous husband Michael Douglas bought the special glass as a prosaic protection against flying golf balls.
The £2-million home is located next door to a busy golf club, where players' shots are often aimed towards the Douglas' new estate. As a result, the couple, who already own homes in New York, Bermuda, Majorca and California, splashed out an additional £60,000 for the special ball-proof measure.
Catherine's parents Pat and Dai, who are currently moving into the house, will be relieved that sudden crashes and flying glass should not form part of their new home routine. But there is still the difficulty of keeping curiosity-seekers at bay.
"Dai gets annoyed at the number of people who try to creep in," said a neighbour following an incident earlier this week when three pensioners approached the mansion and were surprised to be invited in for tea by Pat. "Normally people like this are ejected straight away."
