Puerto Rico-born singer Luis Miguel has been accused of punching a barman following an altercation involving his bodyguard and a drinker in Aspen, Colorado, on 4 January (06).

The AMOR, AMOR, AMOR star, who has won four Grammy Awards, was enjoying a drink with friends at the ski resort's St Regis Lounge when patron William Hayward Hardy approached his table and requested a song, reports PageSix.com.

Hardy requested the 35-year-old sing a song, to which Miguel allegedly replied, "For $1,000." Hardy quickly countered, "I wouldn't give you 50 cents," and walked away.

Later that night, Miguel's bodyguard Julio Cesar Camera reportedly approached Hardy and put him in a strangle hold. Barman Jason Randall Moan then took it upon himself to break up the scuffle.

Miguel allegedly became involved in the altercation and, according to Moan, said, "Do you know who I am?" To which Moan responded, "I don't care who you are, you don't fight in here."

Moan alleges that Miguel then closed his hand into a fist and punched him in the face. Miguel and Camera deny any punches were thrown.
