Kristen Stewart is reportedly suspecting that FKA Twigs is only using Robert Pattinson for fame, International Business Times reported.

Stewart and Pattinson broke up in 2012 after the actress was caught cheating with her "Snow White and the Huntsman" director.  It took awhile for the couple to move on their separate ways. Last September, the actor started dating the budding singer and songwriter FKA Twigs.

The former couple kept the relationship private and avoided interviews as much as possible while Twigs has revealed her feelings for Pattinson to the media. This made Stewart suspicious that the singer is taking advantage of the relationship for fame.

"Kristen was already suspicious of her motives, but when she heard that FKA was straight up talking about Rob to the press, that confirmed it. She knows Rob wouldn't be okay with that. It's so obvious to Kristen that this girl is just taking advantage of Rob, and it really pisses her off. She's still very protective of Rob," the insider revealed.

Meanwhile, Twigs has emphasized how she would like to have a low-profile music career but the relationship with Pattinson put her into the spotlight.

"That side of my life [the paparazzi] is nothing to do with me. That's, like... That is the... side of life of the man that I love. And... when that started happening I had to... Because that is the opposite of who I am as a person, and it was weird," the singer said, The Guardian reported.

Despite being uncomfortable of the situation, Twigs admitted that she accepted it as a part of loving the "Twilight" actor.  

"It's something that's very challenging. I look uncomfortable because I am uncomfortable. But then it's, like, is this person in my life worth that? And he is, without question. Do you know what I mean? In comparison to how happy I am. And how I feel with him. It's 100% worth it. Does that make sense?," Twigs added.

As of this time, Pattinson and Twigs are cozying up in New York wherein, the actor is allegedly planning to purchase a $20 million penthouse.
