McCurdy and Drummond dated briefly in Semptember 2013. The pair's 1-week romance eventually became best known after she accused him of leaking racy pictures of the actress in March 2014.
Drummond denied claims at the time, saying "I want nothing to do with her or the situation. I'm just worried about ball."
