Kristen Stewart Dumping Robert Pattinson for 'Gay Relationship?': R-Patz 'Furious,' K-Stew Romances Katy Perry's Assistant, Tamra Natisin [PHOTOS]

The "cheating" allegations surrounding "Twilight" lovebirds Kristen Stewart and Robert Pattinson continue to swirl... but the National Enquirer's latest report involving Katy Perry's assistant Tamra Natisin really takes things to extremes! Apparently, K-Stew and Natisin have been getting a little TOO friendly in R-Patz's absence... and the "Cosmopolis" heartthrob is completely furious about it! That's right - instead of a budding friendship, the Enquirer alleges that Stewart and Natisin are pursuing a budding ROMANCE.  Are any fans buying into this?

An alleged inside source reveals to the seedy tabloid, "Rob will hit the roof when he sees photos of Kristen and Tamra hanging out together... It's obvious to all of her friends that there's a romance brewing between them."

Just because K-Stew's found a new gal pal doesn't mean that they're hooking up!

But the shady report continues, claiming that the 22-year-old starlet "raised eyebrows by lavishing attention on Tamra" during a fun night out at the Hotel Cafe in Hollywood on March 3.

"They arrived together and spent the entire night talking to each other, ignoring everyone around them," the insider explains. "After a few hours, they left together. Lately, Kristen and Tamra have been spending all their free time together."

How does two girl FRIENDS enjoying a night out on the town suggest that they're in a romantic relationship? If that were the case, there'd be a lot more female couples walking around all over the place!

Still, several sources insist that Stewart seems to have officially moved on from Pattinson. Now that she's found Tamra, she "doesn't seem to be missing" a guy in her life. This coming from a gossip site that repeatedly claims Stewart is "depressed and devastated" with R-Patz being away for so long in Australia...

FYI: The tabloid makes sure to point out that Natisin is very vocal about equality for same-sex couples and even "attended a gay pride rally in the past year."

How ridiculous.

Gossip Cop reached out to a legit source close to Stewart, who totally laughed off the desperate rumors.

Even if K-Stew and R-Patz do "break up," it most likely wouldn't have to do with Stewart getting together with songstress Katy Perry's assistant. Girl are allowed to be "just friends," ya know...
