So where did it all go wrong?!
Well, according to a source, it was Rob's permanent bond with his ex, Kristen Stewart.
“Rob and FKA’s engagement is off. Rob really thought he and FKA would get married, but things have changed. He’s trying to get to a certain level of stardom,” the insider told Life & Style. They also revealed that Rob believes he can learn a lot from K.Stew, “that’s keeping him in LA or on location more than ever.”
Not too long ago, Kristen told Harper's Bazaar UK that she was "deeply in love" with Rob. "Did you think I was faking it? I've always really embraced a duality. And really, truly, believed in it and never felt confused or struggling. I just didn't like getting made fun of," she said of her sexuality.
Although these reports claim that K.Stew is the reason the pair split, she is currently dating Victoria's Secret model Stella Maxwell, and Rob was recently spotted on a date with Katy Perry...
