Robert Pattinson 'cheats' on Kristen Stewart with 'former fling' Caitlin Cronenberg? Twitter fans still support 'Robsten' love, rumors FALSE!

Let's get things straight - Robert Pattinson is NOT hooking-up with married photographer Caitlin Cronenberg! As Mstars previously reported:

UPDATE: Robert Pattinson & Kristen Stewart back together, Caitlin Cronenberg 'cheating rumors' spark relationship drama? 'Twilight' heartthrob smoking again, stress prompts bad habit?

Robert Pattinson recently hung out with "former fling" Caitlin Cronenberg on the movie set of "Life" in Toronto... should Kristen Stewart be worried?

Apparently, R-Patz and the well-known fashion photographer "hooked-up" back in July 2013. They were allegedly spotted kissing while hanging out with a group of pals during a "Maps to the Stars" filming break. In fact, the stunning brunette's father (David Cronenberg) directed the movie! He also worked with the "Twilight" heartthrob on his other major hit, "Cosmopolis."

Anyway, rumors suggest that Cronenberg visited Pattinson AGAIN on-set in Toronto earlier this month. But were they acting flirty?

Apparently not.

An insider for Hollywood Life explains, "They are great pals. There isn't anything happening between them. She just happens to be a girl that he is friends with, nothing more."

In fact, Cronenberg just married lawyer Geoff Grove back in September.

So there you have it, Robsten fans - Pattinson and Cronenberg are just pals! And the stunning brunette wouldn't let the "romance" rumors ruin her big wedding day a few months back. Right before tying the knot, Cronenberg told The Globe and Mail:

"When I first started reading rumors about myself on the Internet it did bother me. You realize that something is on the Internet and anyone can read it. Now, I really don't care. People can say whatever they want about me. I know what's true. The guy that I'm marrying in five weeks knows what's true and that's all that really matters."

In fact, Twitter fans still hold hope of a romantic "Twilight" reunion:

@Pisay_008 : "I miss seeing them together #robsten."

@MPS_Icha: "Love love love ♥ @LoveRKinfinity: Young Robsten are so cute aw aw."

@kissyonline: "New/old bts of Robsten in BD1 wahhhhh that is so sexyyyyy omgggg cant breath hehe hotttt <3."

@robsessedcrisp: "No way, Robsten is unbroken ;)."

@KStewandRPatz: "This happened just four months ago. We shouldn't give up hope just yet! #Robsten."

@KStewandRPatz: "A love like this doesn't just go away over night! #Robsten."

So, who's still Team Robsten?
