The actor is in the country to film Disenchanted.
One Irish woman has been secretly hosting Patrick Dempsey at her home.
The Grey's Anatomy actor, along with Amy Adams, are in Ireland to film the sequel to Disney's Enchanted.
Now, it's been revealed where he's been staying - and it's not at a fancy hotel.
Olivia Burns, founder of Coleraine luxury candle company Olivia’s Haven, revealed that she has been hosting Dempsey.
The Independent report that Olivia shared a photo of herself with the actor on Instagram over the weekend to let the secret out.
"That time Dr. McDreamy stayed at Olivia’s Haven HQ for 2 weeks!" she wrote.
"It has been very surreal going to work and seeing McDreamy everyday.
"We have enjoyed lots of daily chats with Patrick about the beautiful Northern Irish countryside," she said.
She said they were sad to say goodbye to him. The actor has now left their residence, presumably to travel to Enniskerry for filming.
However, he didn't leave without earning the love of her donkey, Neddy!

Olivia said, "P.S. Patrick wants us to set up an Instagram page just for Neddy - what do we think?"
We think Neddy's gonna be Insta-famous soon.
