Jon Hamm went under the radar and completed a 30-day stint in rehab for alcohol abuse last month, and on Wednesday evening we saw the Mad Men star out and about for the first time since he checked out of Silver Hill Hospital in New Canaan, Connecticut.

Hamm kept his head down, and though he tried to cover up his face with the brim of his baseball hay, we couldn't help but notice how gaunt and exhausted he looked. Hopefully he's going to rest up and relax over the next week -- after all, the final season of his hit AMC show premieres on April 6, so he will undoubtedly be attending a number of events to promote it.

Last week Jon's rep confirmed that the actor had checked in (and out) of rehab and said in a statement, "With the support of his longtime partner Jennifer Westfeldt, Jon Hamm recently completed treatment for his struggle with alcohol addiction. They have asked for privacy and sensitivity going forward."

There have been a handful of blind items about the star, and in 2011 The Enquirer ran a story detailing his hard partying ways. "On the set, Jon’s always as sober as a preacher. But when he’s not working, he likes to cut loose with a drink or two… or more! By the end of night, he often seems blotto. His nickname is 'Hammered,'" a source told the tabloid.

We're glad he sought help!

We bet Rob Kardashian is fuming after seeing this new clip from Keeping Up With the Kardashians! In fact, this might be what prompted him to post a photo on Instagram comparing his older sister to "the b*tch from Gone Girl."

In a teaser for this week's episode of the family's reality TV show, Kim Kardashian sits down with sister Khloe and mom Kris Jenner to talk about ways to help Rob, and Kim's suggestion is a bit harsh! "I'm not a therapist. I'm not a doctor," Jenner tells her daughters. "But I do know that we've got all of the resources in the world, and yet he doesn't access."

Kim's reaction? "I think that now what we have to do is everyone back off," she says, while Khloe makes faces indicating that she disagrees. "Everyone licks Rob's a** and does whatever he says," Kim whines. "And it's just at some point, you just have to give it up!"

"We all make his life so easy," she continued. "'Okay, we'll drive you around with a chauffeur so no one has to look at you!' We had a chef on standby, a trainer. 'We'll send people to run out and buy you socks and underwear!' Like, this is pathetic!"

"We're not going to cater to him anymore, but it has to be all of us," Kim says, suggesting that the family cut Rob off. Kris still seems torn about the issue and said, "The other way to look at it is that he has something that maybe he can't help himself."

We were wondering why Rihanna showed up to Jimmy Kimmel Live with a smirk on her face, and now we know why!

On Wednesday the 26-year-old R&B superstar made an appearance on the show, but the previous night she participated in a totally hilarious prank in which she woke up the late night host. Assisted by Jimmy's wife Molly McNearney, Rihanna crept into his house in the wee hours of Wednesday morning with some bandmates and gave a loud (and well-lit) performance of "B*tch Better Have My Money."

Bad Gal RiRi threw money and confetti on Kimmel and then danced on the bed, and we have to say, it looks like Kimmel truly had no idea what was happening. Not only did he appear totally dazed, but he took a moment to remove his mouthguard when he realized what was going on.

When she appeared on the show, Rihanna said, "I am a really big fan of your April Fools' pranks so I was like, 'I want to do that! If I'm going to go on the couch, let's get him back!'" she said. She wins!

Kim Kardashian is finally pregnant again!

APRIL FOOLS! Did we get ya?!

In case you couldn't figure it out -- those pics aren't really of Kanye West's piece. That big-lipped babe is actually her (not-so) single (not-so) white female doppelganger, pregnant Glee star Naya Rivera. But damn does she look exactly like Kimmy K!

The pregnant actress was out and about in la la land earlier today dressed in an all-black, totally Kim-style ensemble.

Hey Kimbo, you better watch your back -- because we have a feeling Naya's starring at it and copying everything about it!

Like many other liberals, Miley Cyrus is not a fan of Indiana's controversial new religious freedom law, which legally allows religious business leaders to discriminate against the gay community.

The "Wrecking Ball" singer took to Time to share her thoughts, which will be published in an upcoming issue of the mag.'

Here are some of them:

I lived a life where I had to be something every day and had to be a character, and it wasn’t necessarily who I wanted to be. And now I’ve dedicated my life to being whoever it is that I want to be, and also constantly learning and evolving.

That’s what’s wrong with [supporters of the Indiana law]—they’re not choosing to live that way. And if you don’t choose to live that way, you’re not going to last in this generation because we are overtaking you. They are dinosaurs, and they are dying off. We are the new generation, and with that will come so much.

We are moving forward. As much as we get distracted by stupid laws that make us feel like we’re regressing, we’re not. We are moving forward because it’s our turn as young people. It’s a new rights movement. There’s so much that young people want to do and change and see, and I think a lot of that can come through social media.

I put something on my Instagram today about how people are trying now to make the Indiana law look like something that it’s not. They’re trying to make it look like it’s not discriminatory. It’s confusing for my fans, so I’m happy to [speak up about it]. They won’t listen to Tim Cook, maybe. But they’ll listen to me, you know? And people are starting to listen, I think.

Let's hope she knocks some sense into people. Maybe she can do some good with that wrecking ball!

Is this a prank or the real deal?

Katy Perry shared this snapshot of her dramatically shorter 'do today on Instagram, and we have to wonder if the pop star is trying to pull an April Fool's Day prank on us!

"✂👦️I asked for the Kris Jenner👦✂️," the singer captioned the photo.

The "Roar" songstress and the Kardashian matriarch have been spending a lot of time together lately, most recently on the Chanel boat cruise, so it wouldn't surprise us if the chart topper got some beauty inspiration from the famous momager!

Posh would never let Mexican food pass her lips!

David Beckham and his sons Brooklyn and Cruz hit up Chipotle for some burritos after a surfing session in Malibu yesterday, and Victoria decided to stay in the car and take a nap instead. She probably had an air sandwich earlier and wasn't hungry.

Sexy Becks and VB are the hottest parents on the planet, but it sounds like they're the most protective too! The father-of-four appeared on The Late Late Show with James Corden on Monday, and told the audience a funny story about being quite the overbearing dad when eldest son Brooklyn wanted to take his crush on a date.

"On his first date, which he was about 14 and a half, Victoria was actually in London. It was Valentine's Day and he said, 'I'd love to take this girl to dinner.' I said, 'OK, great.' I spoke to Victoria and she was like, 'Really?' I said, 'Yeah, he's going to do it.' She said, 'OK. Make sure you take him and make sure you sit in the restaurant.' I was like, 'Really? You're gonna make me do that?' She said, 'Yep. That's the only way I'm going to let him go.' So we took him to a small sushi restaurant and he sat at the sushi bar and I sat about five tables back," Posh's husband dished to the talk show host.

Too funny!

This is going from bad to worse!

Lamar Odom has been battling drug addiction for the past several years, but the former basketball player's problem has gotten even scarier, because he's now experimenting with a dangerous new drug combination called "sherm."

"He has been doing an old-school drug called sherm, which is taking a joint and dipping it in liquid PCP. It’s really dangerous and can make you violent," a source revealed to In Touch.

Estranged wife Khloe Kardashian, who filed for divorce from the former Laker in December 2013, is worried sick about her soon-to-be ex hubby's substance issues. “Lamar’s friends and family and Khloé are all pushing him to get into rehab. Lamar needs serious, serious help,” the insider added.

Please get help, Lammy, because we love you and want you to get better!
