The first is a Western-themed shot, which matches the official trailer currently running on the BBC to promote their return.
The second, meanwhile, sees the couple back in the centre of the Square - and gives an obvious hint of the drama to come as it shows that Kat is heavily pregnant.
Viewers will see Kat back on screen this coming Friday, while Alfie makes his own comeback on Tuesday, September 21.
Soon after fans see Kat's return, there's a twist as it becomes clear that she and Alfie haven't seen each other in quite some time.
Full details of where Kat and Alfie have been and whether Alfie is the father of Kat's baby are currently being kept closely under wraps. However, all will be revealed once both are back on screen next week.
