The footballer is rumoured to be prepared to spend £100,000 on the Aston Martin used by Daniel Craig in the film Quantum of Solace.
An insider told the Daily Star: "Becks is a huge Bond fan and has always wanted to own something classy from the films.
"So when he heard the auction was taking place, he was desperate to bag the car for himself."
However, Beckham is not the only football star expected to bid for the car.
The insider added: "Cristiano Ronaldo also has his eye on it, which might prove to be competition for Becks if they start a bidding war."
The two-door V12 DBS coupe will be the top attraction at Christie's charity auction on October 5.
Money raised at the event will go to children's charity Barnardo's.
