New James Bond star GEMMA ARTERTON is struggling to pay off her student debts - despite looking set to earn millions from her latest role in the superspy franchise. The British actress, 22, has been signed up to play Agent Fields in new 007 movie Quantum of Solace, but insists she isn't letting the financial promise of fame change her spending habits. She says, "I still have student debts to pay off. And I think I've used most of my earnings buying bits from (budget clothing store) Primark."
