It all started when Kristin - who played Charlotte - tweeted SJP - aka Carrie - to say how much she missed her. Alongside her message, she added a photo of SJP at the Sex and the City 2 movie premiere.
Innocent enough, right?!
But then it was SJP's response that had fans going WHAT????
SJP tweeted back: "Me too you! Heard the news? X."
When one fan questioned what news that might be, coy Sarah would only reply: "That news zooming around."
Fans have good reason to be excited though, as just recently Jennifer Hudson suggested a third SATC movie might be happening. Oscar winner Jennifer played Carrie's personal assistant Louise (from St. Louis) in the second movie.
Chatting with Dish Nation radio, the actress revealed: "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."
Oh, we will!
Sex and the City ran for six series on TV before spawning two spinoff movies, the last of which was released in 2010.
