Producers were rumoured to be making plans for a second film last December, before the first was released.
They are now keen to capitalise on the success of the spinoff, which has made around £177.5 million at the worldwide box office.
HBO chief Michael Lombardo said: "There is enormous interest by Warner Brothers Newline to do another Sex And The City, and... they're trying with our help to put that together now."
Rapper P Diddy is thought to be in line for a role in the planned sequel.
