Robert Pattinson and Katy Perry are talking about living together, according to reports.

The Twilight actor recently said he was "homeless" after his parents refused to move out of the LA home he lent them while he was filming in Canada.

Despite reports suggesting Katy doesn't want to get too close to Robert for fear of getting hurt, friends say the 28-year-old actor has been staying with her for the past month.

"They've had a couple of flings, but they're not properly dating," a source told British magazine Heat. "Katy's still in touch with Diplo and Rob Ackroyd [both of whom she's also been linked to recently]. Still, she's in no hurry to move Rob out - they've even talked about living together."

Rob has being residing at the Roar singer's £6.5 million LA home while she's on her Prismatic World Tour. But according to the source, the Brit is also occasionally staying at the Los Feliz house he used to share with former girlfriend Kristen Stewart.

"They have joint custody of Bear and Bernie, their dogs," the insider added. "Rob has keys, but he only goes round if she's away filming."

Rumours have circulated around the status of Robert and Katy's relationship for months, especially after the singer broke up with John Mayer earlier this year. Fuel was added to the fire when he was overheard describing the 29-year-old as "F**king hot" after inviting her to the after party of his movie The Rover.

"Rob and Katy have never stopped being in touch - she loves the attention but also thinks he's really sexy and funny," an insider told Heat previously. "The texting stepped up in January when things started going bad between Katy and John. Rob's been a real shoulder for her to cry on. Since she's been single, though, the texts have hotted up - she loves drunk-texting him and they're always flirty."
