What will Carrie make of this? There have already been rumblings the Sex and the City heroine's relationship with Mr Big will run into problems because of financial strain, and now it looks like she could have a love rival in the second film.
Penelope Cruz has been lensing a cameo for the new movie, and it doesn't look good for Sarah Jessica Parker's on-screen persona.
The Spanish siren was spotted in a sexy backless dress at New York's Empire Hotel earlier this week working on a scene in which she apparently gets a little too close to Big, played by Chris Noth.
Producers have kept details surrounding Penelope's character firmly under wraps, but she's rumoured to be playing a big shot banker.
The Oscar-winner isn't the only famous new name to have signed up. Liza Minnelli has also been added to the cast – though it's unknown whether she'll be playing herself or a character.
And it's been confirmed Jason Lewis – aka Smith Jerrod – will be returning as Samantha's younger ex. The model-turned-actor will be celebrating the opening of his latest blockbuster alongside his former girlfriend, who is now single.
