Holly Madison
isn't letting her pregnancy keep her from hitting the town!

The mom-to-be made two different appearances over the weekend just days before she's scheduled to give birth (March 5).

On Friday, the former Playboy model hit up the Discovery Channel's Museum opening at the Smith Center for the Performing Arts Campus, and on Saturday she made an appearance at Cee Lo Green's  "Loberace" debut at Planet Hollywood in Vegas.

Can we just say we hate Holly (we mean that in the nicest way possible) -- from the front you can't even tell she's nine months pregnant! She's a lucky, lucky girl.

The reality star also told the Las Vegas Sun that she's currently filming a new television special ... and we're guessing her delivery will definitely be apart of it.

We can't wait to see the blonde beauty's baby girl when she gets here (any day now)! Click "Launch Gallery" above to see more pics of Madison's pregnancy.
