Jon Hamm, a man who is mad, and girlfriend Jennifer Westfeldt, a woman of indeterminate anger, have broken up, the couple announced on Monday.

Mad Men star Jon Hamm just finished a 30-day stint in rehab for alcohol abuse, TMZ reports.

Jon Hamm, perhaps the most famous graduate of the The Olde St. Louie Dinner Theater Academy of Dramatic Arts, returned to his hometown last night to throw out the first pitch at a Cardinals game (it was also Bobblehead night).

Handsome man Jon Hamm stopped by The Tonight Show last night, where he and Jimmy Fallon took a look back at their '80s pet cop show, Palisades Park Pet Patrol. It was gross!

On last night's episode of Watch What Happens Live, ringmaster Andy Cohen had his guests Jon Hamm and Amy Sedaris act out an iconic Don Draper/Peggy Olson confrontation from Season 4 of Mad Men. The twist was that Sedaris was made to perform the scene as her former drug addict/prostitute Strangers with Candy character, Jerri Blank. The result was all...mildewy. Unfortunately, though, the scene study did not end with Jerri Blank ugly-crying, as Peggy did on the original episode.

Because Jon Hamm's penis (his Dick Whitman, if you will) gets so much attention, it's easy to miss that the Mad Man also has a gargantuan head. It's so big, in fact, that Saturday Night Live's outfitters have only ever measured one star with a larger domepiece.

Before he was Don Draper, Jon Hamm was a 25-year-old waiter with the floppiest possible '90s hair who went on a terrible dating show. And lost.

Here's the trailer for Larry David's upcoming HBO movie, Clear History. Basically, Larry David's character has a crazy frizzed-out hair-beard combo. He works for Jon Hamm who is sporting a suit, also so wild. Anyways, David's character quits because he thinks Hamm's character is dumb and then he loses out on millions and Hamm is rich and happy and married to Kate Hudson. After a decade of bitterness, David's character launches a madcap revenge plot.

Mad Men star Jon Hamm is furious about being treated like a walking wang.

Jon Hamm's penis: everywhere it goes it causes a big hullabaloo. "It's my world," the penis scoffs, studying its reflection in the mounted vanity mirror,"y'all are just living in it."

Jon Hamm's penis went on a shopping trip to Barneys in New York last Friday, accompanied by Jon Hamm and his lovely girlfriend Jennifer Westfeldt.

Season five of Mad Men ended just as it began: with a question. "When is everything going to get back to normal?" Roger asks Don in the third episode. The presumptive answer was that order, as they knew it, would never be restored—that the characters would instead have to adapt to a new normal as everything changed around them. Season five's thematic through-line was that adaptation. As each character attempted to move forward, they had to find a way to either avoid obsolescence or capitalize on the changing landscape.

Don Draper is no longer Mad Men's hero. That honor now belongs to Michael Ginsberg, the young Jewish copywriter whose work has already upstaged Sterling Cooper Draper Pryce's longtime brilliant creative director.

Last night's Saturday Night Live featured the 100th digital short so we were treated a short about the shorts that featured a bunch of call backs and cameos. Justin Timberlake, Natalie Portman, Jon Hamm and Michael Bolton were on hand to reprise previous roles and Justin Bieber host Will Ferrell joined in as well.

Mad Men Adonis Jon Hamm follows in Hipster Paul Rudd's footsteps to offer the female teenage frequenters of Rookie Mag advice from "a Grown Man."

The Beatles may be the most important band of the 20th century — and feel free to debate that in the comments, even though you're wrong — but their recordings have been notably absent from the TV landscape. Aside from live performance footage, when was the last time you heard a Beatles song used on TV?

Take it for the Sun article that it is, but rumor has it that Jon Hamm and Daniel Radcliffe are set to star as different-aged versions of the same character in a four-part British miniseries that seems to be less a TV show than a diabolical plot by evil librarians to force people to read by causing all TV sets to melt at the same time.

Last night, 30 Rock aired its second live episode and it was both funny and ambitious. Mixed into the show's main plot was a string of sketches that charted the history of television and worked as an homage to live TV. The clip above features a few of those sketches, including great parodies of the Honeymooners, Amos and Andy, and Laugh In as well the work of guest star Jon Hamm.

Raven-haired sock puppet Kim Kardashian has responded to Jon Hamm after he called her "a fucking idiot." Wielding her mighty twitter trident, she posted the following response:

For those of you who needed another reason to crush on Jon Hamm, the Mad Men star joined the ranks of legitimate TV actors ragging on reality TV personalities. His targets: Kim Kardashian and Paris Hilton.
