Sources reveal exclusively to PerezHilton.com that Spencer Pratt was livid when former friend Brody Jenner showed up at his girlfriend Heidi Montag's fashion show and started creating a scene.
"When Spencer found out backstage that Brody was outside and causing drama, he was furious," a source tells us. "He was ready to go out there and get physical with Brody, but thankfully he was persuaded not to by the event organizers."
We're told Pratt is more upset than ever with Jenner.
However, when we contacted Spencer for comment, he played it diplomatically.
Pratt tells PerezHilton.com exclusively, "Although Brody and I have had our disagreements, I find it hard to believe that even he is this desperate for attention. Heidi and I didn't notice him at the show, but if the heckling rumors are true this is a new low to stoop to for fame, even for Brody."
Who will make the next move????
We wanna see these two throw down!
