Los Angeles: OJ Simpson has launched a Twitter account with a video post in which the former football star said he's got a "little gettin' even to do".

Simpson confirmed the new account to The Associated Press on Saturday, saying in a phone interview while on a Las Vegas golf course that it "will be a lot of fun".

"I've got some things to straighten out," he said. He did not elaborate before he said he had to go and ended the call.

Simpson has generally kept a low profile since his release from prison in October 2017 for robbery and kidnapping over an attempt to steal back some of his sports memorabilia from a Las Vegas hotel room.
