Robert Pattinson Spotted with 'Mystery Blonde' Alexandra Warner: Kristen Stewart Break Up Rumors Loom, Did R-Patz Cheat at Australia Music Festival? [PHOTO]

Oh no, Robert Pattinson was spotted hanging out and taking pics with fans at the Big Day Out music festival in Adelaide, Australia on Friday (Jan. 25)... which means he must be cheating on Kristen Stewart with that pretty mystery blonde he was chatting up! No worries, "Twilight" fans, such rumors are most likely totally false. The so-called "mystery blonde" is actually Alexandra Warner, a young woman who innocently posted the fan-meets-movie star pic on Twitter... re-sparking heated rumors that R-Patz and K-Stew are officially donzo. As the break up buzz continues to swirl, Pattison and Stewart repeatedly insist that their relationship is doing just fine...

R-Patz recently jetted off to Australia's Flinders Ranges (sans 22-year-old Stewart) to begin filming the Western-drama "The Rover." Several reports allege that 26-year-old Pattinson called for a "trial separation" before heading down under, and was even spotted enjoying the "single life" with some pals at an Aussie bar.

But what really caught fans' attention was this recent Twitpic posted by Warner:

@WarnerAlexandra: "Casually having dinner with Robert Pattinson :)."

Has R-Patz already moved on... with a girl that appears the total opposite of K-Stew?

Probaby not... although gossip tabloids such as Hollywood Life suggest that's the case.

The fact of the matter is that there's really no "mystery" behind the encounter... Warner's just a fan who happened to run into the "Cosmopolis" heartthrob at the music fest and simply asked for a pic. She later tweeted:

@WarnerAlexandra:"I'm touring with the big day out festival in Australia and he's here. Chilled out bloke. Think he was stoned ha!!"

Fans should remember... Hollywood Life is the same tabloid that once spread rumors that Pattinson was spotted out partying with "mystery blonde" Dree Hemingway back in October... the story was pulled once Hemingway ousted the bogus report.

So to be clear - a "stoned" Pattinson DID NOT cheat on K-Stew at the popular Australia music festival... as of now the two "Twilight" loverbirds are still trying to work things out.
