Robert Pattinson 'Disses' Kristen Stewart, 'Questions Sexuality' HOAX: 'Twilight' Hottie Did NOT Deem Ex 'Lesbian With Ugly Short Haircut' During Drunken Rant

Robert Pattinson and Kristen Stewart are no longer dating - but that does NOT mean R-Patz is a total hater!

Several Robsten fans still hope for a romantic "Twilight" reunion - but at this point, both Hollywood stars are way too busy in their own seperate careers to worry about reigniting a serious relationship.

Well, apparently the 28-year-old British hottie HATES it!

At least according to a recent shady report by OK! magazine - something which GossipCop totally debunks.

An alleged source reveals that R-Patz got a little "drunk" at a recent party in LA, and ended-up bad-mouthing his former sweetheart!

"After a few beers, he started going on about Kristen's new haircut, saying she looks dreadful and that he never would've let her do that when they were together." The insider continued that he "even started questioning her sexuality... given the short cut and the fact that Kristen has really only been seen with girls since their split."

Oh, my.

Rumors once suggested that Stewart was secretly "dating" gal pal Alicia Cargile, but such lesbian hype eventually simmered-down. Pattinson definitely had nothing to do with such buzz.

And he still doesn't.

Another legit source tells GC exclusively that the latest tabloid report is "shameful and wrong."
