Charlie Sheen told a security guard at an ice hockey game to "blow my balls" when she refused to let him back in to the rink.
The former Two and a Half Men star was left fuming after he stepped out of the Staples Center in Los Angeles for a cigarette break and was denied entry to the match on his return.
Shouting at a female security guard, he said: "You know what? F***ing blow my balls, all right, you f***ing asshole."
The actor - who was fired from the hit comedy in 2011 after his outrageous antics – then claimed he had felt that the security guard was being rude to him.
He told TMZ.com: "Have common sense and common courtesy gone in society? That was what I was trying to impress upon her. Let a guy go back in the door he came through."
Sheen (48) then left without seeing the rest of the game, saying: "Bad juju. Clash of the silly." As he walked off he added: "Go Thunder!"
When TMZ approached the security guard, she confirmed that she told Sheen to "f**k off".
Since he has finished filming Anger Management, friends of the star are worried he could start partying heavily again – after his very public meltdown last year.
A source said: "Yes, Charlie is partying. He doesn't want to stop. In his eyes, he thinks, 'I'm having fun, so what?'"
