John Mayer may have admitted to Ellen DeGeneres on her namesake show that his now-defunct relationship with Katy Perry was private as they entered and exited it, but some new details have come to light about why the pair split. While the relationship is dunzo, his feelings for her apparently are not.

"John still very much loves her and has feelings for her," a source with inside info told E! about the former serial dater and cad. "It was just going to be too much with what was on his plate."

His plate is filled with things like his first tour in several years and since his surgery and the Botox injections to repair his damaged vocal cords. Mayer is at a professional crossroads right now, so perhaps he needs this time to focus on his career.

Or maybe they just aren't meant to be together, as there was talk that Mayer's drinking problem -- and he did admit a complicated love of scotch to Ellen -- factored into the split.

Whatever the case, maybe these two cute and talented singers can work it out eventually and Katy, a native Californian, will be his queen again. Or maybe they won't. We'll remain interested in their love lives either way.
