One Tree Hill‘s Antwon Tanner has pleaded guilty to fraudulently selling Social Security numbers, the Associated Press reports. While the actor, who plays Skills on the CW drama, entered a not guilty plea when he was charged in April, he has now admitted in a Brooklyn court that he made $10,000 from the illegal Social Security scheme. Tanner is expected to get up to a year in prison when he is sentenced Nov. 20.
