No, Tom Jones is not relation to Steve Jones, the only similarity is that they are both from Wales where there are a LOT of people named Jones!
Tom Jones has two sons, one with his wife Melinda (Mark Woodward) and one by model Katherine Berkery (Jonathan Berkery).
Actually there are three famous men bearing the name 'Steve Jones', one is a presenter who recently married his long term girlfriend Phylicia Jackson, then there is the biologist and there is also the rock guitarist.
However as biologist Steve Jones is only 4 years younger than Tom I'm pretty sure you were not talking about that one!
Steve Jones the presenter started as a model for Esquire before moving into presenting. He was the first host of the American X Factor as well as presenting various shows in the UK. Apart from the showbiz factor, he has no connection to Tom Jones though!
