A man accused of punching late movie icon Grace Kelly's grandson has been sentenced to 10 days of community service after reaching a plea deal with prosecutors on Monday (04Feb13).

Businessman Adam Hock was slapped with four counts of third-degree assault after allegedly hitting Prince Pierre Casiraghi and three of his friends, including Paris Hilton's ex-boyfriend Stavros Niarchos Iii, following a confrontation at Manhattan nightclub Double Seven in February, 2012.

Hock has escaped a trial after pleading guilty to a charge of disorderly conduct, in exchange for having his record wiped clean.

He has been ordered to serve 12 weeks in anger management and complete a required number of volunteer hours, but the entrepreneur insists he's just happy to put the incident behind him, telling the New York Post, "No hard feelings. Going forward in life. Life's too good."

Casiraghi, the third in line to the Monaco throne, is the youngest son of Caroline, Princess of Hanover.
