The singer recently split from his girlfriend Elen Rivas after a four-month romance but has insisted that the couple will remain good friends.
Writing in his New magazine column, Andre said that he was pleased that journalists had noticed the changes in him at a preview of his new ITV2 show.
"I launched the new series of my reality show, Peter Andre: The Next Chapter, last week and it was really great to watch the first episode with a bunch of journalists and to get their reaction," he explained. "The general feeling afterwards seemed to be that I'm a bit more "frothy" and "fun" these days and I'd have to agree with that."
He continued: "I'm the happiest I've ever been at the moment and I think that really comes across in the show. Please watch it and let me know what you think."
Andre has also revealed that he is working on his new children's book series and has come up with a "great" idea for it.
