Conor McGregor showed off his 'dad shirt' as he plugged his own brand stout.
McGregor is currently in Las Vegas as he films The Ultimate Fighter.
And the Dubliner has not gone into fight camp just yet as he has been busy plugging his own brand stout.
McGregor launched the Forged Irish Stout and it sold out within minutes of its first release.
And the Dubliner shared a snap while wearing a Hawaiin shirt.
Social media users were happy to compliment both the shirt and the stout after sharing the photo.
One user said: "Love the dad shirt".
While another said: "Stout looks great".
McGregor will return to the UFC to fight Michael Chandler later this year.
