Hudson, 33, appeared in the first 'Sex and the City' movie as Carrie Bradshaw's assistant Louise, reported Hollywood Life.
There has been speculation about a possible follow-up to 2010's 'Sex and the City 2' since that film's release, with star Kristin Davis and producer Michael Patrick King recently expressing hopes for a sequel.
"I think it might be happening. Somebody just came to me talking about that. So, if it's in the talks, it might happen. So, look for it," Hudson said.
She also said that she might reprise her role in 'Sex and the City 3'.
'Sex and the City' star Sarah Jessica Parker hinted in January that there is "one last chapter to tell" for the franchise.
The 'Sex and the City' films were spun off from the popular television series, which won seven Emmy Awards and eight Golden Globes.
