The BBC drama released a new teaser ahead of the show's latest installment to their social media channels and have no doubt thrilled them with a glimpse of the Line of Duty actor in character.
In the thrilling short trailer, the Liverpudlian's mysterious character is seen clashing with the Shelby brothers, hinting at troublesome feud ahead.
As ominous shots of the Peaky Blinders are shown, Graham's character voice is heard saying: "I hear there's some man here from Birmingham looking for me."
Understandably fans of the series took to Twitter in their droves to share their excitement over Graham's long-awaited appearance.
One fan penned: "OMG! Stephen Graham in Peaky Blinders!!! 2022 is gonna be a good one".
"Cillian Murphy and Stephen Graham in a TV show together is the best thing to ever happen on TV," another commented.
"I thought Peaky Blinders couldn't get any better, but then Stephen Graham appears in it," a third shared. "Simply amazing stuff.
A fourth added: "Wow this looks sooooooo good. Actually so excited to watch the new series."
Earlier this month, fans were treated to another teaser for the upcoming sixth season.
The clip was posted by director and producer Anthony Byrne. "Can't wait for you all to see more. And more is coming very soon," he teased.
Fans were collectively shook after watching the seven-second clip, which features Ada Thorne (played by Sophie Rundle) tell Thomas Shelby ominously: "Take a good look Tommy because one of us isn't gonna' be here for long".
The upcoming series, which has been confirmed by showrunner Stephen Knight to be the very last of the Brummie gangster drama, is set to premiere next year.
Although the end is near, Steven Knight has hinted that a Peaky Blinders spin-off show could go ahead without actor Cillian Murphy's iconic character.
Although he admits it would be "impossible" to imagine the current Peaky Blinders show without him, he isn't ruling it out for future spin-offs.
Knight told Birmingham Live: "In the form it is in, it is absolutely impossible for this to work without Cillian. As it grows and progresses, who knows?
"There may be worlds that are part of the Peaky world that are about someone else but he is the centre around everything orbits.
Peaky Blinders returns in early 2022 on BBC One and BBC iPlayer.
