When it comes to And Just Like That... nabbing a music superstar for a role in season two, the writing's on the wall. 

On Instagram Feb. 22, Sam Smith posted a photo of themself coming out of a trailer on the set of the Sex and the City sequel series.

Dressed in a grey sweatshirt, jeans and sunglasses, the singer captioned the pic: "Up to something unholy on set."

The caption is a reference to Sam's No. 1 hit "Unholy," their song with Kim Petras that earned them both a Grammy earlier this month. 

The image was cross-posted to the official And Just Like That... Instagram page, which suggests that Sam's new collab is official. E! News reached out to HBO Max for comment and has not heard back.

If Sam does indeed make an appearance, they'll join a growing list of guest stars set to co-star alongside SATC favorites Sarah Jessica Parker, Cynthia Nixon and Kristin Davis on season two. 

In October, it was announced that Tony Danza was joining season two of And Just Like That... as the actor playing the father of Che Diaz (Sara Ramirez) on Che's new sitcom.

And, after months of rumors, HBO Max confirmed last month that John Corbett would reprise his Sex and the City role of Aidan on season two. Not only that, Parker—who played his former lover Carrie—posted photos Feb. 10 of the rekindled lovers kissing in an upcoming scene.

Maybe Sam is playing the wedding?

For everything else we know about And Just Like That... season two, keep scrolling.

Kim Cattrall—who starred on all six seasons of Sex and the City and its two spin-off movies, but did not reprise her role for the first season of And Just Like That...—will make an appearance on the revival's second season, a rep for Max (formerly HBO Max) confirmed to New York Post on May 31.

If you just couldn't help but wonder what's going on with Carrie and Aidan, this February 2022 photo of Sarah Jessica Parker and John Corbett acting out a scene for season two might give you an idea.

In August 2022, Deadline reported that John Corbett—who played Carrie's boyfriend Aidan on seasons three and four of Sex and the City—would be returning for "a substantial, multi-episode arc" on season two. In January, Max officially confirmed Corbett's season two casting with first look photos.

Corbett won't be the only fresh face in season two, as Tony Danza is also joining the cast as the actor playing Che's father in her sitcom pilot.

In a Nov. 3 photo from the And Just Like That... set, Carrie was seen wearing her iconic Vivienne Westwood dress from her wedding to Mr. Big (Chris Noth) in the 2008 Sex and the City movie. 

Do we hear more wedding bells?

Charlotte's beloved dog Elizabeth Taylor was noticeably absent in season one, which left some fans befuddled. Charlotte did have a new bulldog named Richard Burton, but it didn't quite feel right that the legacy and impact of Elizabeth went unaddressed. 

In season two, a wrong appears to have been righted. In a Nov. 15 Instagram post, costumer designers Molly Rogers and Danny Santiago shared an oil painting of Elizabeth Taylor wearing a Burberry sweater, writing, "On charlotte's hallway wall."

Kristin Davis even commented, "My first baby."

May she rest in peace.

While season one of And Just Like That... was an undeniable nostalgia rush, it was a bit....bleak. An entire season centered around death and grief will do that.

However, the second season promises a breath of fresh air, at least according to Sarah Aubrey, Max's head of originals.

"What you're seeing this season is all of these characters embracing life," Aubrey told Variety Nov. 10. "It's a very joyful season and I think, in some ways, it feels like iconic Sex and the City episodes."

Season two will premiere on Max on June 22.
