If you've been watching The Hills lately, you know that Spencer and Heidi Pratt are at odds about whether to have kids. (Spencer entertained the idea of getting a vasectomy on last week's episode, and Heidi's about to fight back with a night of contraception-less seduction.)

We truly hate to take sides since they're both equally (and awesomely) outrageous, but we can't help but wonder: what's the rush, Heids? The jet-setting, uber-famous couple just tied the knot -- and it's not like babies are always bundles of joy. Case and point: Alexa Chung attempted to drop a drooly little fella right onto the their laps during today's live show ... but Heidi didn't have her Tide stick on hand. Check out the full interview with MTV's very own Lucy and Desi.

It was surprising enough when Kelly Cutrone told Alexa Chung on Monday that she came thisclose to being Madonna -- but yesterday, Roxy Olin may have one-upped KC by shedding her steely exterior and getting SUPER embarrassed (i.e. beet red) during a game of Truth or Dare. Believe it or not, this too-cool-for-school chica actually danced a sexy solo jig on stage and then downed some anchovies while Alexa poked fun. Hey, it was good to finally see Roxy's softer side! Check out the Truth or Dare segment below, plus after the jump, watch Alexa's interview with the People's Rev PR girl to find out how she landed a spot in front of The City cameras, as well as what Spencer Pratt was really like in high school!

Not only was she a wild party girl back in the day, but long before Kelly Cutrone became The City's bitchy boss lady, she was poised to become a pop star (or was it death metal?)! That's right, a contract with Atlantic was signed, sealed and delivered, and an album was even produced. But apparently, Kelly couldn't contain her hunger for total control fashion publicity and ended up becoming the first person in history to walk away from a record deal in order to start a PR company.

While she refers to her departure from the music biz as a "bad decision" in this interview with Alexa Chung, we all know the truth: Kelly Cutrone was born to make interns cry. Check out the video to hear what else she told Alexa about life before Whitney Port showed up at her doorstep.

It's not easy to get under Alexa Chung's skin. But after watching a sneak peek from My Super Psycho Sweet 16, the MTV talk show host damn near lost her mind. Take a look at what's got Alexa running around like a chicken with her head cut off, then tune in tonight at 10pm to find out what happens when the biggest rager of the year turns into an evening that's to die for. Trust us -- it's gonna be a scream ...

Vogue Evolution may not be dancing on the ABDC stage anymore, but that doesn't mean they're done spending time in front of the cameras. The popular-with-the-people crew (eliminated on Episode 5) swung by It's On with Alexa Chung yesterday to give fans a flashy reminder of why we heart them so hard. Check out their live performance and get a quick lesson in cat-walking with sass AND class!

Remember that cringe-worthy episode of The Hills in which Kelly Cutrone a.k.a. Scary Boss Lady invited Stephanie Pratt to People's Rev for an internship interview ... and then quickly proceeded to skewer her like a shrimp kabob? Of course you do, that moment was hard to forget. And if your memory is as clear as ours, you'll recall that Cutrone tested Steph's proficient French skills (as stated on her resume) with some unreciprocated parlez vousing.

Well, during today's It's On with Alexa Chung, Steph made a point of admitting that she's actually more well-versed in 'Franglais,' an English and French hybrid that's commonly used by natives of France. Yet when put to the test by the show's practically fluent host, Pratt barely got a word in edgewise. Foiled again! Check out the entire interview to hear Stephanie come thisclose to proving she's a Franglais expert, plus get her reaction to Heidi's Miss Universe Pageant performance and the new division between the female cast of The Hills (to be witnessed on the much-anticipated Sept. 29 premiere!)

With a new show out and a new album on the way, you'd better believe Diddy's getting his self-promotional game on. And earlier this week, Puffy P. Diddy the Bad Boy hit up the It's On with Alexa Chung studio to trade dance moves, talk bitchassness and give fans the lowdown on Making His Band. Watch the mogul/artist/motivational Twitterer impress Alexa with his patented head-nod (and defend his p-p-p-poker face), plus hear him explain why he's ready for a tight new backup band ... that won't ditch him for Jay-Z.

With16 and Pregnant's upcoming reunion special scheduled to tape at the end of this week, some of the series' teen moms have already arrived in NYC and are making the most of their brief stay. No, they're not shopping at FAO Schwartz or taking horse-and-buggy rides through Central Park -- this is a business trip! -- but Farrah, for one, is using the opportunity to share more of her story with MTV viewers.

Check out Farrah's visit yesterday to the set of It's On with Alexa Chung and hear her discuss why she originally agreed to be filmed for 16 and Pregnant, as well as what's happening with Baby Sophia!

Last Monday, Olivia Palermo and Whitney Port chatted it up with Alexa Chung -- separately -- fueling a bit of speculation that the City frenemies may have officially crossed over into full-on enemy territory. Nevertheless, both ladies were more than pleasant around us, even seconds before show time. Below, check out video that our behind-the-scenes cameras caught of 'Liv and Whit getting prepped and primped ... uh, nowhere near each other.

It's not easy pulling off a daily, LIVE talk show. Aside from cramming down an hour's worth of new material while pop music blasts and producers pull their hair out, Alexa Chung's gotta sit still as a statue (post triple-shot of espresso) while professionals work to "make her look normal." Her words, not ours.

Watch this behind-the-scenes video of what it's like on the set of It's On with Alexa Chung with just one minute and thirty seconds till airtime...

BUT BTDoubleU: Through all the chaos and commotion, Alexa always manages to keep her cool (and wicked sense of humor). Watch her break into song after a successful hair and makeup sesh, straight after the jump!
