Robert Pattinson & FKA Twigs 'Official' - Kristen Stewart's Ex Confirms Dating Buzz, Holds New Girlfriend's Hand During Romantic Venice Beach Stroll [PHOTO]

Robert Pattinson's not usually the type to flaunt any sort of "PDA," so things must be getting pretty serious between the "Twilight" heartthrob and his new rumored girlfriend, FKA Twigs (real name, Tahliah Debrett Barnett)!

UPDATE: Robert Pattinson & FKA Twigs 'Smitten,' Kristen Stewart Soothes Heartbreak With Nicholas Hoult? After Romantic Venice Beach Date, New Couple Cruise Hollywood

Apparently, Kristen Stewart's ex and the aspiring songstress have been dating on the "down low" for several months now. Initionally, fans were shocked to hear that the "Water Me" singer might be pregnant with R-Patz's baby. Yeah - not true.

But it does look like the two are romantically involved.

According to GossipCop, "The Rover" actor was spotted on a casual stroll in Venice Beach over the weekend - and he wasn't alone.

Pattinson was walking hand-in-hand with Twigs.

Of course, fan-captured snapshots started going viral on Instragram and beyond:

The "couple" hit the boardwalk with a group of friends - but clearly they were more focused on spending time with each other.

The pair were initionally spotted together in NYC earlier this month.

Are Twitter fans jealous?

@indieLINDSEY: "Rob Pattinson has a new girlfriend and she's not me. :("

@threelilbirdsss: "Is it catty of me to be happy Rob Pattinson has a new girlfriend only because it will piss off his ex who I can't stand? Probably so huh. Ha."

@somerslays: "Robert pattinson has a new girlfriend, i'm happy for him <3"

‏@JewelFen: "D*mn, I need to work today. Twitter is just about to be getting interesting. Robert Pattinson and new girlfriend. *grabs popcorn.*"

@brian_yossy: "@FKAtwigs hey i'm serious, are you really the girlfriend of ROBERT PATTINSON?? Oh my God, I'm really not believ[ing] that. :("

Twigs remains much more active on social media compared to Pattinson, but she has yet to respond to such romance rumors on Twitter or Instagram.

And K-Stew also remains mum, altough some Robsten fans are probably disappointed.
