Nicole Richie a skinny b*!%#?

The Hills star Spencer Pratt and Good Charlotte singer Joel Madden had to be forcibly separated after a huge fight at the Beverly Hills Hotel on Saturday afternoon reports IN TOUCH.

Spencer, 23, confirmed the run-in exclusively to In Touch but insists it was all a misunderstanding over Joel¹s pregnant girlfriend Nicole Richie.

He told in Touch: "I was sitting having a quiet lunch with Heidi when Nicole walked in and started pointing at me and then whispering to Joel.

He storms over and starts shouting, "you been talking s*#% about my girl!"

I told him, "Please can we not do this at the Beverly Hills hotel. This is ridiculous."

Both Joel, 28, and Nicole, 25, were later escorted out of the hotel, according to an eyewitness.

Spencer, however, claims he never said anything derogatory about Nicole.

He said: "It all stems from an interview in Details ages ago where I was misquoted calling Nicole a skinny b*!%#. It's all a misunderstanding. I've always thought she's a really nice girl and I wouldn't call her that."
