Well ,the rumor mills is working over time trying to decide if Nicole Richie is pregnant again or brawling in Vegas. Some reports coming out of Hollywood state that it looks like Richie may have bun number two in the oven. Yet in the middle of these baby questions, it seems Nicole may have been caught brawling in Vegas after a night of partying. If this is the case, it may help to put the baby rumors to rest. Of course, it could be possible that she’s pregnant and fighting and her next public appearance will be on the Jerry Springer Show.

When Nicole was spotted wearing a flowing lilac “maternity style” top, people started wondering if she was expecting again. According to one onlooker “The top was not something Nicole usually wears. She ordinarily goes for tight T-shirts and vest tops. The other unusual thing was that she was wearing comfy sheepskin boots and not her usual heels - the boots definitely looked like something a pregnant woman would wear.”

So apparently in Hollywood if you decide not to dress like a hooker for once, you’re pregnant? Wow. Guess if I was in Hollywood I would have been pregnant for, oh, the past 25 years or so. Did you ever think that maybe she was having a bad style day? Or actually a good style day? Or she was having a fat day and felt that she looked like she weighed more than 80 pounds. Or, yes, she may be pregnant. But didn’t she kinda where hootchie mamma outfits when pregnant with Harlow?

Pregnant or not, it seems Ms. Richie may have been caught in a slight snafu in Las Vegas while waiting for valet parking. According to eye witness reports (and we know how reliable they can be) Nicole got into an argument with a woman while both were waiting for their cars outside Hard Rock Hotel.

One onlooker said, “Nicole started fighting with this woman while they were both waiting for the valet to bring round their cars. She ended up being so rowdy that she was escorted off the property by security.”

According to Nicole’s peeps, this is totally untrue. “Nicole was in Las Vegas but there wasn’t an altercation of any kind involving her.”
