FORMER Lowerhouse professional and current Australia star Ryan Harris has apologised for a drunken Twitter rant he sent in the early hours after being refused entry to Crown Perth casino while celebrating Australia's Ashes victory.

The croaky-voiced paceman said sorry after arriving in Melbourne.

"Obviously I made a silly mistake this morning and I tweeted something I probably shouldn't have,'' he said.

"It was a silly thing to do - they let me in in the end, so they did the right thing.

"But they have to do their job and they were doing it.

"As I've heard many times before, don't tweet when you've had a drink.''
