Latin Night also typically brings out some serious ruffles.
Lets see how they perform under pressure.

Daddy YankeeAs Nikki puts it, she went from Nana to J.
On Ballroom Night, Nikki was an elegant princess.
On Latin Night…lets just say most princesses wouldnt be caught wearing Nikkis skimpy getup.
Or maybe they would.
Surprising both Nikki and her partner, Nikki has some trouble getting into the sexy routine.
She giggles any time she gets too close to Artem.
I mean, his abs are laughably perfect.
She needs more of the samba bounce and to be stronger and more flexible in her legs.
Len is already hating on all the gyrating.
you oughta use your hips in the rumba!
She also gets flowers and a thank you note from Taylor Swift for dancing to her song last night.
Thats a pretty solid birthday.
I mean, aside from Len being extremely unhappy with Vals choreography.
Len doesnt see enough or any, really traditional rumba content.
Hes a traditional guy, and he always will be.
Typically a smiley guy, Derek is trying to harness some aggression and power.
To do so, he pictures sparring against Kobe Bryant.
Sharnas way prettier to look at, but whatever works, dude.
In just one night, he is already dancing bigger.
How about that solo section?
Thats intimidating to take on for week two.
Although the judges are all happy to see Dereks determination shine through, his scores are pretty low.
Cant a guy catch a break?
People are just the worst sometimes, huh?
After a few tears, Sasha is all smiles on the dance floor.
Who is this person?
She is confident and sexy and also, Ive never been to a prom like this one.
Even Crankypants Len noticed an extra sparkle in Sashas dancing tonight.
Carrie Ann applauds Sashas polished technique, but even more so herflair.
First, men do not remember any details about their first dates with a woman.
On the dance: The judges have mixed reviews.
Carrie Ann saw the passion, but Len was not feeling it at all.
Nick knows he needs to work on his tight hips, but Len pretty much wants a top-to-bottom overhaul.
Isnt Latin Night supposed to be fun?
He is all of us.
Jordan knows the samba is a tough dance to tackle, but he is so game.
Once again, the judges praise this partnership.
I think were all just used to seeing Lindsay with someone double her age.
Nevertheless, they all feel the energy and vibrancy coming from this couple.
gnashThe couple that spray tans together stays together.
To help Drew get the feel for a sexy rumba, Emma sprays her guy down.
Shes had enough of those pale abs.
It must be magic spray tan, because Drew has never looked so in control on the floor.
and tells him this rumba is his best dance to date.
Young ThugNow, this is what Latin Night is all about.
Its steamy and sexy, and they dance on top of a table.
What more do you want?
She needs stronger footwork and to work on extending her legs.
Honestly though, the way this evening is going, if Len is happy, you should be content.
Demi Lovato and Stefflon DonIn rehearsals, Vanessa is having some trouble matching the energy of the samba.
Maks wants her to channel her inner-20s party girl.
Our little Mama kills it.
She and Maks are having a blast out there, and it shows.
Len is so impressed, he tells Maks to keep Vanessa focused because shes a real contender.
It seems a little soon to say it out loud, but were all thinking it.
Still, a little criticism cant dampen Vanessas mood.
I never knew I could have so much in common with a professional football player.
Am I an athlete now?
Boy was bringing it.
Lindsey was pretty good, too.
This was a stripped down, fast-paced, classic salsa…with a Ballas spin, of course.
I thought I saw some clunky arm passes, but the judges were simply wowed.
Carrie Ann says something about Lindsey not dancing to the music, but being the music.
My notes for this dance were just high-pitched squealing.
Who is this person?
He is living his best life.
We are all living our best lives by watching it.
On the Latin Night chopping block are Nick and Peta and Debbie and Alan.
It would be sad to see either couple go!
Too soon, America!
