The duo, who train at West Hollywood's Unbreakable Performance Center, are not serious, reported Us magazine.
According to a source the 23-year-old "Give Your Heart a Break" singer is "just having fun and is still looking to meet new guys."
The former Disney star and Wilmer Valderrama released a joint statement on June 3 to announce that they had parted ways.
Valderrama, 36, says that he has moved on from Lovato- but his focus is on his career. And he has no complaints about his life post-split.
