Robert Pattinson and Kristen Stewart may have starred in one of Hollywood's greatest relationship meltdown last year but recent rumors say that the two have kissed and made up since then and are now hooking up again. In fact, news from various sources even say that the two are living together again in L.A.!

Rumors about the two started when Pattinson called himself "homeless" in an interview with Jimmy Kimmel. Sources say that the Twilight actor doesn't have a place in L.A. and sometimes stays at Kristen's place in Los Feliz when he is not at Chateau Marmont, IBtimes reports.

But can fans of the two really rejoice now that the two are rumored to be back in each other's arms again? Apparently not as trouble seems to be brewing in the horizon in the form of a potential love triangle.

And the girl who is supposedly getting between the reconciliation of the two? None other than Dark Horse singer Katy Perry herself.  

According to Classicalite, the pop singer is not a fan of Robsten getting back together. In fact, an insider spills that Katy even urged the Edward Cullen actor to stay away from Kristen. The source dishes, "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."

On the other hand, some think that the singer's comment may be a little too biased. Reports say that Katy and Rob have been very close friends and had their romance brewing for a long time already. The pair reportedly even spent a weekend together and had plans for last Easter as well. The three, however, seems to have had good history together when the young couple spent their time partying with the pop star at the Coachella Valley Music Festival last year, the Examiner reports.

So, for Robert Pattinson's fans, allow us to ask: Are you team Kristen Stewart or team Katy Perry?
