Kristen Stewart has reportedly been losing her friends over her ego, following her three-year relationship with Robert Pattinson.

A close friend of the 24-year-old actress revealed to Radar Online that Stewart is now completely different to how she used to be when they were younger, even referring to her ex-boyfriend.

"Kristen doesn't even resemble the person that we knew from before she was with Rob," the friend said. "She used to be a very low-key, cool girl."

The friend also made it seem like dating Pattinson has "inflated" Stewart's ego.

"But her inflated ego has convinced her that even her childhood friends only want to hang out with her because of 'who she is,'" the source said, adding that Stewart is much different than who she used to be. "It's really sad, and her friends are literally dropping like flies."

Meanwhile, the "Twilight" stars recently sparked reconciliation rumors, as they both were in Canada.

The pair called it quits after Stewart was caught cheating on Pattinson with her "Snow White and the Huntsmen" director Rupert Sanders. Ever since their split, the 28-year-old actor has been dating FKA twigs.

Pattinson was apparently following the British singer on her European tour, but Celeb Dirty Laundry reported that he left her and flew off to Toronto to begin filming the upcoming action-thriller movie "Idol's Eye."

The website added that Stewart was reportedly in the same town as Stewart, where the former couple's relationship first began, to promote her new films.

Although a source denied their reunion speculation to Gossip Cop, insisting that the report is "a crazy rumor. Just not true," they added that Stewart certainly "plays enough of an obstacle" between Pattinson and his current girlfriend, especially because the ex-couple "still keeps in touch."

In addition, Stewart recently announced that she plans to take a break from acting, after starring in seven films in two years.

"I'm going to take so much time off. I'm going to buy a live-work space in downtown LA, and I'm going to make some (stuff) with my hands," she told USA Today. "Literally, I made that decision a few weeks ago. I'm making a short film. I'm making a bunch of (stuff). I don't know how I'll put it out. But I'm not going to hold it so preciously close to me. I write all the time."
