The 35-year-old singer is believed to have been approached to play a fashionista in the new film when shooting begins next month.
Posh has previously revealed that she was offered a part in the first movie - but turned it down because filming clashed with rehearsals for the Spice Girls reunion tour.
A source told The Mail On Sunday: "She really wanted to be in the last movie but wasn't able to take part because of her commitments with the Spice Girls. This time she's keen to take part."
Beckham has already tried her hand at acting in the past. As well as appearing in the Spice World movie in 1997, she has filmed a guest appearance in Ugly Betty and recorded a voice role for SpongeBob SquarePants.
