It's hard to top Justin Bieber and Kristen Stewart's, but this is still HIGHlarious!
Jimmy Kimmel strikes again with his "Celebrities Read Mean Tweets" segment, this time with Jessica Simpson, Jessica Alba, Zach Braff and so much more.
LOLz, and the best reaction award goes to Elisabeth Moss!
Check out all the celebs and their mean tweets (above)!!!

Peggy Olsen, what are you wearing?!?
Elisabeth Moss was spotted leaving the studios of Jimmy Kimmel Live yesterday and she was dressed EXACTLY like all the Hollywood Boulevard tourists lining up to snap her picture!
Don't get us wrong, the Mad Men actress is a shinning, shimmering, splendid example of a super seXXXay woman, but this is not her finest look!
We love jorts and flip flops just as much as the next gal, but — no, wait. We don't!!!
Lis, you're rocking a wicked body and a wonderful smile; get thee to a stylist!!
LOLz!! Maybe her outfit wasn't that dramatic. She clearly cleans up nicely as is evident by her recent sultry

Peggy Olsen may have started out as a demure, sometimes coquettish young girl, but the big city has turned her downright scandalous!
Why, now she's playing F*ck, Marry, Kill!
During her seksi GQ photo shoot, Elisabeth Moss was asked to choose between Mad Men's Don Draper, Roger Sterling, and Pete Campbell. She says:

Is it just us, or is Don Draper totally pulling off the Blue Steel look?
Either way, we can't think of a better person to grace this month's cover of Rolling Stone than Jon Hamm!
He, Elisabeth Moss, January Jones, and Christina Hendricks did a Mad Men cover shoot back in 2010 for the magazine's annual television issue, but now Jon is flying solo for the first time! With a face like that, one has to wonder how this hasn't happened sooner!
In a tiny sneak peak of what to expect in this issue, the actor looks ahead to the show's finale in 2014 and says it hasn't always been easy being the bad guy:

Vincent Kartheiser has been acting for 20 years, but proposing to Alexis Bledel gave him one big case of stage fright!
So what's a veteran actor to do? Rehearse, obvi! But with whom?
Well, when you're surrounding by so many ridiculously attractive people, who can pick just one? Vincent practiced his proposal on his Mad Men costars Elisabeth Moss and Jessica Paré! Jessica says:

When you have costars like January Jones and Christina Hendricks, it's easy to be left in the fashionable dust, but not if you’re Elisabeth Moss.
Peggy made sure to stand out Wednesday night at the Mad Men season 6 premiere in El Lay by showing off her girls in a black McQ dress.
You know it's a good dress when you manage to out-boob Christina! LOLz!
Elisabeth completed her boobilicious outfit with a metallic Charlotte Olympia clutch and Sergio Rossi heels.
Well done, Peggy!

Mad Men starlet Elisabeth Moss arrived on the red carpet of the 2013 SAG Awards looking a bit too casual!
While you can really never go wrong with a black dress, this one looks like it would be better suited for a cocktail party than an event like the SAGs!
Maybe she should have saved this Dolce & Gabbana number for the after parties!
She’s definitely rocking those million dollar diamond earrings, though!
