Season 3 is still being filmed, but the drama has already begun.
Yes, fans. The Hills are very much alive ...
... with the sound of cat fights.
Insiders claim that the publicity-crazed Heidi Montag is so eager for more face time on the hit MTV reality TV series that she's been crashing scenes with former BFF, Lauren Conrad.
"Heidi's been showing up at shoots uninvited," a source tells Us Weekly.
That news is about as surprising as Britney Spears wearing awful outfits.
Heidi knows her best chance for airtime next season [which premieres in August] is to be in sequences with Lauren Conrad."
The drama came to a head May 30 after Heidi Montag, 20 - who recently got engaged to Spencer Pratt, 23 - clashed with Conrad, 21, at an L.A. nightclub.
"Lauren was screaming, 'You're pathetic!'" says a witness at Les Deux, where the fracas went down.
"Lauren was using her hands wildly, saying she didn't want to deal with Heidi."
"Heidi's recording her album. She doesn't have time to chase Lauren."
Yes, Heidi Montag is recording an album. We're guessing it will be a huge seller... up there in quality with the newest Lindsay Lohan compilations. If that.
