Robert Pattinson & FKA Twigs Loyal, Why Songstress Won't Cheat On Boyfriend Like Kristen Stewart: 'Twilight' Ex-Girlfriend Harbors 'No Hard Feelings'

Kristen Stewart really hurt ex-boyfriend Robert Pattinson when she cheated on the British heartthob with "Snow White and the Huntsman" director, Rupert Sanders a few years ago. But now the 28-year-old "Twilight" cutie is currently dating aspiring songstress FKA Twigs, and there's no way she'd prove disloyal...

An alleged insider tells the infamous gossip webloid HollywoodLife.com:

"Tahliah is a very private person, like Rob. 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. Loyalty is a must for her in a relationship and she just wouldn't cheat on Rob, or anyone."

Maybe that's just what R-Patz needs!

The snitch goes on to explain why Twigs is the perfect match for Pattinson (especially after so much heartbreak):

"She has the utmost respect for herself, for Rob, and she has a tremendous amount of integrity."

Do MstarsNews readers agree that they make a cute, happy couple?

Meanwhile, rumors suggest that K-Stew's also moving-on romantically... with "Equals" co-star, Nicholas Hoult (the ex-boyfriend of Jennifer Lawrence).

And she definitely doesn't harbor any hard feelings towards Pattinson's new girl:

"Kristen sees Rob as a high school relationship. It was something that she will remember forever but she has moved on," another alleged source tells HollywoodLife.com. "She is now in her college years, so to speak, to discover the woman she actually has and wants to become. She pays no attention or cares who FKA twigs is and only hopes the best for Rob... To say that she is jealous or thinks about him or anything along those lines is not really accurate. She has her own life to live."

Hopefully things work out for both members of the former Robsten!
