Jones is the highest-rated Welsh star, with an estimated £140 million to his name. He is 14th in the list, which is headed by Zomba/Jive Records co-founder Clive Calder.
For the second year running, Katherine Jenkins has topped the top 20 list of young British music millionaires aged 30 or under. The singer has an estimated fortune of £13 million. However, as she turns 31 next month, it is the last time Jenkins can feature in the list.
