Conor McGregor got so fired up about revealing a donation to a charity he loves on Wednesday night that he straight-up dropped an F-bomb live on TV!!!
The UFC superstar appeared on Fox News' "Hannity" to announce a $1 million donation to Tunnels to Towers -- a charity created following the 9/11 tragedy to help families of emergency responders who die in the line of duty -- when he got a little too excited.
Speaking with the org's CEO, Frank Siller -- the brother of 9/11 hero Stephen Siller, who lost his life trying to save others in the World Trade Center attack -- McGregor couldn't help but utter a cuss word.
