Swift's rep, Tree Paine, tells PerezHilton.com:
Wow. Wow. Wow.
Kanye is straight-up INSANE!!!!!
On top of his "humiliating" public cheating scandal, he's dating the Sexiest Woman Alive so friends say Demi is "jealous and frustrated."
Fortunately, friends say Demi is getting "through it" and is working toward moving on with her life the same way Ashton has.
Unfortunately, she's still a little bitter.
Tis life, Demi. Set sail on your own new adventure. Enjoy your own new piece of arm candy. LET GO!
