The New York Daily News reports Usher was happy to greet O.J. Simpson at his Kentucky Derby party in Louisville early Saturday morning, but not his girlfriend. After inviting the Juice to the VIP corner, “O.J.’s girlfriend kicked Usher in the leg,” according to a spy. “Usher didn’t know she was with O.J., but when it happened, his security threw her out of the party.” Simpson then had to go outside to convince security to let her back in. Usher was then making news on derby day, after being asked who his pick was to win thoroughbred racing’s biggest event of the year. “I’m here for the photos, that’s it,” he said.
