These two are more on and off than Rihanna and Chris Brown ... and that's really saying something!

Before jetting off to Munich, Germany for the next stop on his Believe tour, Justin Bieber visited ex-girlfriend Selena Gomez at her Los Angeles home, reports Us Weekly. The Biebs dropped by around 3:30 p.m. on Wednesday, and his security team and driver waited outside while he spent about an hour with Selena.

Not sure what they chatted about, but we're guessing his battery investigation had to have come up in the conversation! Bieber is currently being investigated for battery against his neighbor, and while a source close to the pop star's security team tells X17online that "there was no physical altercation" between the two, it's being reported that Bieber hocked a loogie in the man's face!

When we polled X17 readers yesterday, 89% of you said you wouldn't be surprised if the bad boy pop star did spit in his neighbor's face, while 11% of you still believe that his neighbor is a hater who wants to tarnish his reputation.

Bieber chatted with Us Weekly about making headlines, and he told the mag, "The biggest misconception about me is that I'm a bad person. I get upset about that ... I'm young and I make mistakes. That's part of growing up. I mess up sometimes. It's part of growing up. I know who I am and I'm not gonna let negativity towards me bring me down. I'm a positive person and I plan on staying that way."
