Conor McGregor has bizarrely hijacked Sydney Sweeney's social media post promoting her new film, Immaculate.
The horror film releases on March 22 and has received positive reviews so far, with Rotten Tomatoes giving the picture a 70 per cent rating.
Sweeney, who recently starred in the divisive Marvel film Madame Webb, has been promoting her latest work on Instagram.
She shared a picture of herself on the red carpet on Instagram and said: "IMMACULATE march 22nd."

But McGregor has hilariously decided to hijack the post by promoting his own film, Road House.
"@roadhousemovie March 21st," he commented, showing zero regard for Sweeney's movie in the process.
McGregor's hilarious response has amused fans on social media, with one user tagging the UFC icon and saying: "The promo on the promo is genius lol."
A second said: "Atta boy."
A third said: "@thenotoriousmma bro is promoting like a g."
A fourth stated: "What's my goat doing here."
And a fifth reacted to McGregor's comment by saying" Smoked."
McGregor has made his name in sport but has recently made his acting debut in Road House, which is a remake of the 1989 Patrick Swayze film of the same name.
And the 35-year-old may receive a Guinness World Record for appearing in the title.
McGregor claims he is the highest-paid first-time actor of all time, dwarfing Dwayne 'The Rock' Johnson in the process.
He recently said on X: "What did you think of my acting debut movie trailer? Hell of a ride!
"I am now officially the highest-paid first-time actor of all time, on record, pipping Dwayne Johnson for the top spot. Incredible!"
McGregor has since deleted the post.
Johnson, who made his name in wrestling, was paid a huge £4.3million for appearing in 2001's The Mummy Returns.
That feat saw The Rock receive a Guinness World Record as a result.

But if McGregor's comments are accurate, he could be set to take the accolade for himself.
The UFC icon was recently asked about his acting career in an interview with Good Morning Britain.
He said: "That’s the fact, the highest paid first time actor of all time so it’s a nice feather in the cap.
"There’s not an action star in Hollywood that could take me on and that’s a fact, so let’s see how it goes."
McGregor stars alongside Jake Gyllenhaal in Road House.

And Gyllenhaal has joked they had to remind McGregor that the film needed fake fighting, instead of the real thing.
"It was a bit scary at times," he told LadBible.
"I mean, that first time where we go face to face, I was definitely intimidated, but then I thought to myself, the game level that he works at, with the skill that he has, it’s really, ultimately, a mind game, right?
"And they’re all playing it with each other all the time, and what I had, though I didn’t have the skills, what I did have was the experience in my field, so when we met in that moment, I tried to bring my history and my experience from my different field to him in that moment - and I think that’s what you see in that first shot."
He added: "He was guiding me through the grappling and he was giving me instruction in how to choke him out and do all these things, but ultimately… and I had to say to him a couple of times, like, remind him, ‘Remember, we’re in a fake fight, don’t actually punch me’ and he was like, ‘Oh yeah, right, right, right’
"And in those moments, where he’s, 'Right, right right’, you go, ‘Jesus, oh s**t’, but it was good fun."
