The Sex and the City
sequel just got a little more glamorous.
Along with the original fab four – Sarah Jessica Parker
, Kim Cattrall, Kristin Davis and Cynthia Nixon – Penélope Cruz
and Liza Minnelli are both appearing, along with Jason Lewis, who reprises his role as Samantha's younger ex.
Despite previous reports, Cruz doesn't play herself in the film, which is due to hit theaters next summer. For her cameo, the Oscar-winner fills the designer shoes of a banker, a source tells PEOPLE.
Cruz's character may spell trouble for Carrie (Parker). Clad in a sexy backless black dress, Cruz was spotted at New York City's Empire Hotel earlier this week filming a scene in which she gets a little too close to Mr. Big, played by Chris Noth.
Minnelli, meanwhile, filmed for three days on the Manhattan set. When she wrapped, she broke into a rendition of "Every Time I Say Goodbye" for the cast and crew.
"A total hush fell over the set. You could have heard a pin drop, it was such a moving moment," says an on-set source. "Everyone had goose bumps, tears. It was a really lovely parting gift she felt like giving everyone."
