Robert Pattinson and Kristen Stewart reunion rumours have been circulating on the web for quite some time now. The latest reports also indicated that the former couple is now living together in Los Angeles.

Even though Twilight fans would love nothing more than to see their favourite Hollywood couple reunite, not everyone is thrilled about the possibility, reports Classicalite.

According to a source, who spoke with Life & Style, Pattinson's 'good friend' Katy Perry has urged him to stay clear of Stewart:

"Katy has told Rob that she thinks it's a really, really bad idea for him to reunite with Kristen. Katy warned him that Kristen will end up hurting him again," the source said (via CelebDirtyLaundry).

Perry could, however, be a little too close to the situation to comment. A source, who spoke with The Sun, claims that their romance has been going on for a while now:

"Katy and Rob are the best of friends with a very strong sexual chemistry. They care a lot about each other but have always been careful not to upset Kristen. But Kristen's off doing her own thing and accepting it's time to move on. Katy and Rob have been hanging out all weekend and making plans for Easter, too...Friends genuinely want to see them get it together properly".
