On April 2011, he was seen with actress Halston Sage. He is described as a very private person, so nothing was confirmed or talked about. After months of speculation of the relationship, on April 2012, he confirmed the relationship. During Big Time Rush's tour on 2012, he said he was single, but on January 2013, the relationship was again confirmed, when he said that they've been together for "on and off times for the better part of 2 years". By May 2013, Maslow confirmed that the relationship was over since "this is a time to work."
