Is Sam Smith going to be making an appearance on "And Just Like That..."?
On Wednesday, the singer posted a photo of themselves on Instagram emerging from a trailer, with the caption "Up to something unholy on set" -- a reference to their Grammy-winning No. 1 hit "Unholy" with Kim Petras.
The photo was cross-posted on the official Instagram site for the HBO Max series, which is a sequel to "Sex and the City."
