Kristen Stewart Ignores FKA Twigs' Taunts, Disses 'Joke' Ex-Boyfriend Robert Pattinson After Wedding Invite Snub: New Alicia Cargile Romance Confirmed?

Rumors suggest that FKA Twigs won't allow Robert Pattinson to invite any of his "Twilight" pals to their upcoming wedding, obviously including ex-girlfriend, Kristen Stewart. But the 25-year-old "Still Alice" starlet could really care less - she's having too much fun with BFF (turned romantic partner?) Alicia Cargile!

The two ladies have been spotted spending ample time together throughout LA, and an alleged source tells the Daily Mail: 

"[They are] living together and act like an old married couple."

And looking back now, K-Stew basically laughs-off her relationship with the 28-year-old British heartthrob.

Another supposed snitch tells the infamous gossip webloid Radar Online that Stewart is too happy and content to worry about Pattinson's current engagement:

"As far as [ex-boyfriend] Robert Pattinson goes, that is just a joke. Kristen could care less what he does, who he is with, or where he lives."

So, are things actually getting serious between the "Camp X-Ray" beauty and Cargile?

"Alicia and Kristen love each other very much, and it shows by their constant affection towards one another," (via kpopstarz.com).

"With Alicia, Kristen does not have a facade. Very few people can actually get to know the real Kristen and that is how she likes it. But when Kristen is with Alicia, there are no walls around her. She not only acts like herself, but she is also incredibly genuine because Alicia brings out the best in her." 

The insider concludes:

"Kristen acts like a little girl when they are together and there is really no putting words on how happy her friends are to see her happy. Kristen is finally in a relationship where she is just loved unconditionally, but not because she is a movie star."

Perhaps this is the perfect fit for Stewart - Robsten's Hollywood "fame" was probably a bit too much for either star to handle. Apparently, Twigs has nothing to worry about!
