Conor McGregor has issued an apology to his fans who haven't been able to get their hands on his new whiskey.
The MMA fighter released his own whiskey brand earlier this year.
According to his PR company, Proper No. Twelve Irish Whiskey has sold hundreds of thousands of bottles since its launch.
The distillery bottled what was estimated to be enough product for six months of sales in Ireland and the United States, but this hasn't been enough to deal with demand.
Conor McGregor says plans are in place to have the product restocked in Ireland before Christmas.
He also says the brand is launching in the UK, Australia, New Zealand, Russia, and Canada in 2019.
