In honor of tonight's True Life (True Life: I'm Having Twins), we thought we'd round up a list of Hollywood's most famous birthday-sharing siblings. But after a few minutes of brainstorming, we realized that wasn't as easy as it sounds. Sure, we've all heard of the Olsens, The Veronicas and Good Charlotte brothers Benji and Joel Madden. But most of the twins we dug up were celebs with nonfamous twinsies (like Jon Heder, Ashton Kutcher and Alanis Morissette)!

+ Think you can come up with any famous pairs (Jason and Jeremy London, Tia and Tamara Mowry) that we forgot? Tell us your fave twosome (ours is still Arnold Schwarzenegger and Danny DeVito!) then read up on all the celebs mommies who are seeing double.

We know, we know, Paris' trashy hat/sunglasses getup wasn't exactly a fashion tour de force. But you can't be a style icon without taking a few chances, and at the risk of sounding like Desirae, we didn't totally hate it. Sure, it was slightly ridic and old ladyish -- but nothing like the homeless/septuagenarian concoctions Mary-Kate Olsen wears. Besides, ditch the Claire's Accessories (i.e. cheap shades and fedora), and it's totally almost wearable! (Or at least WAY less Boca Raton Barbie.)

+ Think Paris' outfit was an accidental slam dunk? Or a MAJOR fashion don't? Take our (anonymous!) poll and let us know whether Paris' over-the-top ensemble was a train wreck -- or a trend in the making.

Olivia Palermo's been known to rock cocktail rings, designer suits and perfectly coiffed curls on The City. But that didn't stop the immaculately groomed social from hitting the red carpet last night in a flowy, bohemian style gown, with dangly earrings and stick-straight hair to match.

+ Think she's going through some sort of high-class hippie phase (a la M-K Olsen)? Or just cuttin' loose -- and letting her hair down? We're not sure, but either way, it agrees with her. We haven't seen Liv this happy/relaxed since, well, ever! Or at least not since Whitney came to town...

Although we're (admittedly) biased, we love what we've seen from Whitney Port's flirty/floral fashion line, Whitney Eve. But apparently, not all the critics agree. Case in point, the New York Daily News is arguing that Whit's flowery pleated-front shorts are both overpriced (they're going for $245) and uncannily similar to a pair of silk bubble-shorts from the Olsen twins' Elizabeth and James line (priced at $200).

+ Think they're stretching for a story? Or is Whit selling her customers short? Check out the pix at the NYDN web site and let us know if you'd be caught in Whit's clothes.

With House of Style making its triumphant MTV return (catch it tomorrow afternoon, at 3pm!), we started thinking about all our favorite famous-faced designers who've helped take fashion into the mainstream. So who's got the talent to take the runway by storm -- and who shouldn't quit her day job? Take our poll and let us know how these six celeb-turned-stylistas stack up!

You know what I love more than anything? House sitting. It’s amazing. You just sit around and play with the cats and watch TV on DVD and eat all the food in the house because it’s probably gonna go bad anyway. Sadly, in this economy, house-sitting jobs are few and far between, so when I heard Lil Mama was out of town judging America’s Best Dance Crew, I figured I’d do her a solid and offer my services for free ... without asking her permission. Big mistake!

All things considered, Lil Mama was a pretty good sport. She just wanted a little honesty. So, I told her what I had been up to in her crib:

1) Reenacting my favorite scenes from New York Minute with my M-K Olsen cutout.
2.) Programming Lil Mama’s DVR to record the Slap Chop infomercial every time it airs. (She's so Punk'd!)
3.) Dressing up as Diddy in Lil Mama’s fur coat -- and various assorted bling -- and staging my own version of Making The Band starring my favorite new act, the Xylopholks, which features a skunk on xylophone and a pink gorilla playing the upright bass. (Don’t believe me? JUST WATCH THE RECAP!)

She was so into it. Do I see a collaboration coming down the pipeline? Fingers crossed! OK, gotta run -- I think I’ve outworn my welcome. I better jet before she notices that all her Mini Snickers are gone.

Jennifer Lopez and her impossibly-thin hubby Marc Anthony are reportedly having SERIOUS marital probs. (Fact: an anonymous insider alleges that Anthony once called his wife's post-baby body "chubby!") So what's a girl to do? According to Star magazine, that would be secretly run back to her ex-boyfriend, Diddy, for help.

Which totally makes sense! After all, they did date a lifetime ago (back when Diddy was known as "Puffy" and Jennifer was known as J.Lo) and lately, he's been chock full o' sympathy for all his old friends. Take, for instance, these warm sentiments he recently shared about former pal Lil' Kim (who's gone on record blasting the Biggie Smalls biopic, Notorious):

The worst part about screwing up tends to be the awkward post-screwup apology. Which is why nothing impresses me more than someone who's willing to face the music and admit he was wrong. And today, The Hills' Spencer Pratt is that someone.

Turns out, the guy a heart (almost) as big as his bank account. The future Mr. Heidi Montag stepped up to the plate and apologized to Mary Kate Olsen for overreacting to her comments on the David Letterman show. "I apologize for getting caught up in trash talking," Pratt told Usmagazine.com, "but she brought up an emotional subject when she mentioned the soccer stuff."

Now that's what I'm talkin' about.
