He also said that now that the teen is 18 years old, he and Jones "are free to be together" and pointed out that they left the courtroom together.
Deters declined to discuss details of their current relationship, saying that the pair would discuss it on the "Today" show and "Dateline" on Friday.
He said that Jones will not try out to be a Bengals cheerleader in the future, and that for now, she's working as a legal assistant in his office.
Jones has expressed interest in becoming a lawyer and is studying to take the Law School Admission Test, he said.
Before any accusations involving the student surfaced, Jones drew public attention when she sued a Scottsdale, Ariz.-based gossip website over a posting dated Dec. 7, 2009, that included her photo and was headlined "The Dirty Bengals Cheerleader." The posting claimed that Jones' ex-boyfriend cheated on her with more than 50 women, contracted chlamydia and gonorrhea, and likely gave it to her.
Another post on the site, Thedirty.com, accused Jones of having sex in the classroom and said, "Why are all high school teachers freaks in the sack?"
Jones resigned as a teacher at Dixie Heights and from the Bengals cheer squad in late 2011 after four years with both jobs. Deters said at the time that she had done nothing wrong and stepped down because a rumor that she had become involved with a student became too much.
The lawsuit, which accuses the website and its creator of defamation and invasion of privacy and seeks $11 million in damages, was on hold until the criminal case was resolved.
Deters now is asking for a January trial date in the matter.
Jones' mother, former school principal Cheryl Armstrong Jones, also pleaded guilty Monday, to a misdemeanor charge of attempted tampering with evidence. She admitted to the judge that she sent the teen a text message telling him to get rid of his phone and also avoided jail time.
