Kristen Stewart's career may be blossoming with a number of new films, but it looks like her personal life may not be in the best shape it could be.

Kristen Stewart & Robert Pattinson Make Brief Connection In Magazine Interviews?

On Sunday, Radar Online reported that the actress has apparently changed since she was younger, but not in a good way; a childhood friend of hers supposedly stated that Stewart has become too full of herself and was not like this before she dated her Twilight co-star Robert Pattinson.

"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."

"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 continued by adding that the actress is different from 'who she was.'

Unfortunately, it sounds like Stewart might be losing some of the people who care about her.

"It's really sad, and her friends are literally dropping like flies," the insider said.

If this information is true, then it's likely that the actress doesn't care about something like this since she recently expressed her happiness to USA Today where she mentioned how she's doing.

"I'm really happy right now, overly happy," she said. "I'm definitely not looking furtively- I like to look around at (stuff). I feel great. I'm not overcoming fear right now."
