Kristen Stewart is reportedly convinced that she can't compete with Katy Perry for Robert Pattinson's affections, with the Twilight star said to be worried about her ex's musical connection with the Firework singer.
Kristen and Rob split last month after a tumultuous few months which stretched back to KStew's affair with married director Rupert Sanders almost a year ago.
Since the split, Rob has been spotted spending an awful lot of time with the pair's mutual pal Katy Perry, sparking rumours of a romance born out of friendship. And according to inside sources Kristen seems resigned to the fact that her ex and Katy are made for each other:
"[Kristen] knows Rob's met Katy's parents now, and seeing them on dates is really hard," an insider claims to Heat magazine. "She knows that when it comes to Rob's passion for music, she can't compare to Katy, so seeing them laughing away at a concert is devastating."

Earlier this month, Katy and Robert attended a Björk concert together where they tried to keep things low-key, even arriving separately to divert attention. However the source claims that once the pair were inside rocking out, it was hard for them to keep their blossoming relationship under wraps:
"They were clearly into each other," a source explained. "They were standing very close together giggling into each other's ears - they barely stopped touching."
The insider adds that Katy is well aware of Rob's recent relationship drama and is attempting to keep things "fun and light" after a waring few months with Kristen:
"At the moment, Katy's trying to keep things fun and light - hence the concert, rather than a romantic dinner. They're not at the boyfriend-girlfriend stage. They're just friends who have been attracted to each other for a while, are single and can finally do something about it."

Meanwhile it was reported earlier this week that 23-year-old Kristen is furious with Rob ater he seemingly moved on so quickly with one of their joint pals: "Kristen was never fully comfortable with Rob and Katy's relationship. She always suspected he had a soft spot for her," a source told Grazia.
"She's furious that the pair seem to have got together without so much as a word to her. She seems paranoid that something could have gone on before she split with Rob."
