Robert Pattinson has been linked to just about every Hollywood beauty under the sun following his split from Kristen Stewart last May. Luckily for Robsten fans, one report is now alleging that the “Twilight” co-stars are secretly dating.

According to a print report from the July 7 issue of InTouch Weekly, Pattinson, 28, recently spent the night with Stewart, 24, at her Los Angeles abode on June 12, the same day he was allegedly spotted flirting with 29-year-old pop singer Katy Perry at "The Rover" film premiere. “Pattinson secretly spent the night with his ex Kristen Stewart,” reported the tabloid, an “insider” adding that the “very close” pair “definitely hooked up.”

While the “Twilight” co-stars are speculated to have rekindled their three-year romance (One which unofficially ended last spring following Stewart’s rumored affair with her married “Snow White and the Huntsman” director Rupert Sanders, now 43, in 2012.) insiders claim the duo won’t be publicly reuniting anytime soon despite Stewart’s desire to do so.

“She still loves Rob and would love to be with him again,” a source said of Stewart’s feelings for the British film star. Unfortunately for the “On the Road" actress, Pattinson, who has been spotted out-and-about with everyone from “Birthday" singer Perry to model Imogen Kerr in recent months, reportedly isn’t as interested in monogamy. “He’s having fun and doesn’t want to be in a committed relationship right now,” the insider said.

The tabloid's report follows Pattinson’s confirmation to the Hollywood Reporter last month that he's still in contact with his former off-screen girlfriend. “Oh, yeah,” the actor responded “blithely” when questioned if he still speaks to Stewart, later denying a request to discuss her rumored affair. (He won’t talk about any of that, explained the magazine.)

While news of Pattinson and Stewart's communication may have thrilled some of the most die-hard “Twilight” fans, OK! Magazine published claims in May suggesting that the actors recent conversations may not have been so friendly. According to the tabloid, Stewart allegedly left Pattinson a scathing voicemail following rumors he was dating their mutual friends.

“She flipped out on his voicemail,” a source said. “Kristen thinks Rob is hooking up with them purposefully to punish her for the way their relationship ended and she’s ticked.”
