Where some have claimed the two are keeping it casual and it's all still very much in the air, a source close to Katy exclusively tells Hollyscoop the details on what to expect.

"Katy and John are definitely going to get back together," the source said, adding that it didn't work out because she wanted something much more serious than he was able to give her. "She is an extremely jealous person and he was over it."

John did seem pretty committed to the split when he confirmed on the Ellen DeGeneres show that the media was "correct" to say they were done.

However, actions speak louder than words, and lately John's actions speak volumes concerning a fresh start with the pop singer.
