Robert Pattinson, FKA Twigs vs. Kristen Stewart 'Tortured Soul, Don't Give A F*ck' Turn-On: 'Twilight' Hottie Follows New Girlfriend's Concert Tour Before 'Idol's Eye' Filming [PHOTOS]

Does Kristen Stewart have anything in common with Robert Pattinson's new girlfriend, FKA Twigs?

Apparently, the two beauties have similar personalities that really turn the "Twilight" heartthrob on.

And it has nothing to do physically.

An alleged HollywoodLife.com insider reveals:

"She's [Twigs] a very powerful woman... She just has this presence and this don't give a f*ck attitude, just like Kristen has." 

The snitch continues:

"In a lot of ways T and Kristen are very similar... They're both kind of tortured souls, they don't care about fame or being well liked, they're both extremely passionate and obsessive when it comes to their work. All of those things are huge turn ons for Rob." 

The major difference - the "Two Weeks" songstress won't cheat on Pattinson (the act which ultimately ruined Robsten when K-Stew hooked-up with "Snow White and the Hunstman" director Rupert Sanders a few years ago).

Another source explains, "She's not the type to take a relationship lightly... She takes a commitment very seriously, and above all else, she is a very loyal person." 

Even so, Twigs wouldn't have the opportunity to "creep" anytime soon - she's basically attached to R-Patz's hip!

The 26-year-old singer is currently touring throughout Europe - and the 28-year-old actor's been spotted at several of her recent shows (including Paris and Brussels). Things are definitely heating-up between the two lovebirds...

And just over the weekend, the new Hollywood couple arrived in Germany together - check out the paparazzi photos here.

According to GossipCop, Pattinson is scheduled to begin filming the new movie "Idol's Eye" soon, so may have to leave the side of his current muse for awhile. But Twigs will perform in North America this November - so perhaps Pattinson will follow her to the States?
