Kristen Stewart lesbian RUMORS 'amuse' Robert Pattinson's ex: 'Twilight' beauty NOT dating BFF Alicia Cargile, 'laughs off' girlfriend buzz

Rumors initially suggested that "Twilight" sweetheart Kristen Stewart "dumped" on-and-off again boyfriend Robert Pattinson for another chick:

Kristen Stewart lesbian? Twitter fans respond to 'dating new girlfriend Alicia Cargile' RUMORS, Robert Pattinson break-up confirmed?

Apparently, K-Stew finds such same-sex dating buzz downright hilarious. The "SWATH" beauty isn't a lesbian - if such rumors were indeed true, she'd have no problem admitting that she digs the ladies!

An alleged insider tells ShowBizSpy.com:

"Kristen couldn't stop laughing when she saw the reports she's in a lesbian relationship with Alicia... She said, 'If I was a lesbian, I wouldn't hide it - it's nothing to be ashamed of! Alicia and I are just good friends! That's all.' Kristen and Alicia have been having a good giggle."

Just because 24-year-old Stewart enjoys spending more quality time with her BFF does NOT mean that they're romantically involved. Maybe she's just sick of all the boy drama, and needs some girl time!

Are fans still hoping for a Robsten reunion? Both K-Stew and R-Patz are very busy with their separate careers at-the-moment, so don't really have the time for a recommitted relationship. But considering Stewart definitely doesn't have a girlfriend, maybe there's still a chance!
