What a relief! The 46-year-old star took to his Twitter account later on in the day to let his fans know that he was fine after the scare

Witnesses said that the actor was having a hard time breathing before the incident occurred.

The gossip site reported that a rep for Verne informed them that he was brought to the hospital as a precautionary measure.

One of the 2feet 8inch actor's fans posted a photo of herself on Instagram posing with Verne as she explained in the caption she was there to witness the horrific moment.

Just moments before: Instagram user @oqtimusqrime posted this shot of herself with the actor along with the caption: 'Verne had a seizure earlier right in front of me, but I have heard that he is resting back in his hotel'

Friendly to fans: The 2feet 8inch actor certainly seemed to be having a good time at the event as he posed for a shot with America's Top Model contestant Adrianne curry and a male fan

Signature role: Verne is best known for his role as Mini-Me in the Austin Powers series

The user named @oqtimusqrime wrote: 'Verne had a seizure earlier right in front of me, but I have heard that he is resting back in his hotel. I'm so glad he's okay!'

She went on to describe the chaotic scene: '! I'm not sure exactly what happened, just know that he got really tired and started seizing and spitting up blood. So scary, my heart stopped!'

Later on in the day, Verne made sure to let his followers know that he was doing just fine as he posted on Twitter: 'Everything's ok guys. Thanks for the concern.'

The actor burst on the scene as a clone one-eigth in size to baddie Dr. Evil in 1999 sequel Austin Powers: The Spy Who Shagged Me and the following film Austin Powers In Goldmember.

He has enjoyed a steady acting career including roles in Harry Potter And The Sorcerer's Stone, The Imaginarium of Doctor Parnassus and even a stint on VH1 reality show The Surreal Life.

No doubt Verne has a big sense of humour about his small size as he posted a photo on Instagram for St. Patrick's Day on Tuesday of himself wearing a green shirt with 'World's tallest leprechaun' emblazoned on it.

Last week he even shared a snap of him standing next to a life-size figure of Star Wars Jedi Master Yoda with the cheeky message: 'Freaking Yoda's taller than me.'

Good humour: The actor often shows off his self-deprecating sense of humour on his social media accounts as he showed off a shirt that read: 'World's tallest leprechaun' earlier this week
