British popstar Rod Stewart has been charged after allegedly punching a hotel security guard outside a children's party in Florida, according to a police report obtained by US media.

The 74-year-old singer of "Maggie May" was with his family at Breakers Hotel, Palm Beach, on New Year's Eve when he was refused access to a party in the children's section of the resort, according to US media on Friday.

Stewart was attempting to enter the event with his 39-year-old son, according to the police report.

The ex-singer of the Faces -- recognizable by his hoarse voice and blond mop of hair -- was charged with simple battery, a minor offense which is generally punishable by a fine.

He is scheduled to appear in a Palm Beach court on February 5. (Text, excluding headline, courtesy of AFP)
