Showing off their festive sides, Audrina Patridge and Christina Milian spent last night partying it up at Hypnotiq's Hollywood Halloween party held at Les Deux.

Looking as if they co-ordinated costumes beforehand, the Gonna Tell Everybody singer and The Hills actress schmoozed it up with their fellow revelers throughout the evening.

Before heading out, Audrina responded to recent comments about her MTV hit show, which claimed that the whole deal is staged.

Ms. Patridge tells, “Everything is real. Lauren and me are real friends. We live in our apartment. That's real, like where we work, everything. The situations are real.”

Meanwhile, Audrina does admit producers “tweak it a little bit” by suggesting they go certain places. “I mean, they might be kinda like, ‘Okay, we want you to go to Les Deux tonight,' so we go and whatever happens, happens. And they might do things to tweak it a little bit, but our reactions – it's totally real. It's reality.”
