The British crime drama follows a group of teenagers living on the streets of Victorian London. In Arthur Conan Doyle's Sherlock Holmes novels, the group of teens, who lived on Baker Street, earned cash from the detective by finding out information he couldn't access himself.
But in the Netflix series, the teens who work for John Watson to solve supernatural crimes, for which greedy Sherlock takes all the credit.
And while fans have been gripped by the series itself, twitter seems suspiciously awash with tweets about one character, and one character only: Leo.
Yep, the thirst is real.
Actor Harrison Osterfield plays Leopold - a rather handsome prince and a close friend of Thaddea Graham's Bea, the leader of the Irregulars.
And as they watched the hunky actor alongside the rest of the cast on screen, it's safe to say that fans were crushing rather hard.
One wrote: "No thoughts. just Leo. #TheIrregulars".
A third joined many in pointing out the actor's resemblance to James McAvoy.
"Harrison Osterfield is just a young James McAvoy. I can't unsee it #TheIrregulars," they wrote.
Meanwhile, another also shared a picture of the actor, writing: "I watch #TheIrregulars for the plot. The plot: [picture]".
Us too, hun. Us too.
Leo is a royal by status, but he clearly feels trapped within the confines of Buckingham Palace.
He's also been diagnosed with haemophilia, which means that even if he gets a minor injury, he could die.
His diagnosis saw Leo shrouded in protection - a move which is meant for his safety, but ultimately pushes him to run away.
Alongside Osterfield, who has also starred in the likes of Avengers: Infinity War and Catch 22, the show's star-studded line-up also includes Henry Lloyd-Hughes (Indian Summers, Harry Potter and the Goblet of Fire) as Sherlock and Line of Duty star Royce Pierreson as Doctor Watson.
Thaddea Graham (Us, The Letter for the King) stars as Bea while Darci Shaw (Judi, The Bay) appears as Jessie, Jojo Macari (Sex Education, Hard Sun) joins the lineup as Billy while Ansu Kabia (The Long Song) appears as John Cooper.
"Set in Victorian London, the series follows a gang of troubled street teens who are manipulated into solving crimes for the sinister Doctor Watson and his mysterious business partner, the elusive Sherlock Holmes," a synopsis reads.
"As the crimes take on a horrifying supernatural edge and a dark power emerges, it'll be up to the Irregulars to come together to save not only London but the entire world."
