"
The City" gal
Whitney Port and "
Jersey Shore" girl
Sammi "
Sweetheart" both hung out in Las Vegas this weekend.
Question is ...

A few uninvited vermin had
Whitney Port running for the door of her own apartment -- and no, we're not talking about a visit from
Speidi.
TMZ has learned "
The City" star put herself up in two different swanky NYC hotels this week after she and BFF
Joanna Scapa found an unwelcome party of mice creepin' around her pad.
We're told the gals didn't even bother to change out of their PJs -- immediately booking it to the
Cooper Square Hotel while still in their jammies.
Whitney's been waiting it out there and at the nearby Bowery Hotel ever since.
She'll return home once exterminators finish doing their thing.
Her show may be fake, but
Whitney Port proved she's the real deal when it comes to rockin' a
wet bikini.

The 24-year-old "
The City" star soaked her bones at a Miami hotel pool on Monday.
Believe it or not, this shot took just one take.
Anyone else think Whitney Port's hair accessory looks like a giant bird dropped a giant dump on her head? Anyone?
Whitney Port is either very easy to pick up -- or she just gave this guy -- who totally hit on her at LAX -- the following phone number: 310-735-0099. Try it.
Whitney Port is interested in a career in fashion -- and her personal fashions certainly are
interesting.

"The Hills" castoff pulled some cash out of a Beverly Hills ATM yesterday -- she should use it to pay her grandmother for the clothes she stole out of her wardrobe.
Despite the scorching temperatures in L.A. this weekend, "Hills" star Whitney Port still had a nippy lunch at the Ivy.

Whitney's wardrobe malfunction turned the Robertson Blvd. eatery into the best breastaurant in the world.
A shiny metallic top fused with a skirt resembling the lamp from "A Christmas Story" is just not working on Whitney Port.

We bet Audrina told Whitney that getup made her look skinny and stylish. Somewhere in a posed-to-look natural photo-op, Heidi and Spencer are laughing.
Whitney Port has some image-crushing friends -- LC's sidekick's buds were heard yelling some extremely embarrassing confessions outside Hyde last night.
Heidi Montag's starting to look like a positively good pal, now isn't she?
Lauren Conrad -- and her dress -- needed a little help staying up after a night of partying for her 22nd birthday.

Cameras snapped her spilling out of her car and her dress as she arrived home from S Bar last night. It was a regular "Hills"-apalooza
earlier at Katsuya where TMZ also caught L.C. and Whitney, Audrina and Lo, and ... you know, whoever else.
