Scheana couldn't believe Stassi would judge her after getting with Frank.

Scheana's birthday boy looks pretty pleased with his cupcake and his lady.

Katie explains that being a real friend means telling Stassi what she doesn't want to hear.

Stassi doesn't see what the big deal is, lots of people want to get in her pants.

Maybe it was best that these two rode alone.

Don't worry, these guys have ducky all buckled up.

Preparing for a short-staffed Saturday, Lisa almost had to throw on a SUR dress and wait tables herself.

Check in was a little awkward. OK, a lot awkward.

Stassi's reaction to the flowers did not bode well for a reunion with Jax.

"To a hell of a weekend" was right.

The best way to celebrate a birthday: Chippendales.

We like all the girls dance moves, but Katie's might win.

The guys look like they're having a blast.

There were two shows going on at the Chippendales.

Things got a little crazy at SUR, but were about to get even crazier in Vegas.

Just when we thought this gang was finally getting along. . .

JAX attack!

Do not tell someone to f---- off on their birthday, Tom Schwartz (especially Princess Stassi).

Peter missed his true calling: as a Vegas dancer/bouncer.

Was it just us, or did that escalate quickly? So much beer on so many people!

"You said you loved me!"

And off goes Tom's shirt! Cool pants, bro.

Why was Jax wearing a sweater, anyway?

First rule of Fight Club is apparently take off your shirt.

Jax had some colorful things to say to Frank.

"Shirtless animals in a parking lot!"

Jax tries to understand how things went so wrong, or maybe worries about his white sweater getting dirty from that Vegas parking lot.

Stassi left alone with no Frank, no Jax, no friends, and no ride.

Stassi was gonna have fun with or without Katie and Kristen.

What else could you wear on your birthday, but your birthday suit?

You have to get close to stay warm when skinny dipping.

Looks like Stassi picked up some moves from the Chippendales.

Stassi did not want to talk! She just wanted to have a good time!

Stassi takes a dance break to tell her BFFs that they make her depressed. And on her birthday, too!
