“We have decided to do one last season to really do the story justice,” he said.
When reached for comment on Sunday, a CW spokesperson said “no decision has been made” in regards to the show’s fate.
“The Vampire Diaries” is about to wrap up its seventh season, with the finale to air on May 13. The show was picked up for an eighth season earlier this year in the CW’s sweeping renewal of nearly all its shows into the 2016-17 season.
Somerhalder’s announcement comes just days after series star Kat Graham revealed that season eight would be her last.
“Season eight will be my last season,” Graham, who plays Bonnie Bennett, told Us Weekly. “I just hope that whatever I do after, the crew can come with me. … The crew is going to be the hardest thing to let go, because we are a family.”
“The Vampire Diaries” also saw a huge departure with the exit of Nina Dobrev, who left the series in season six.
