Twitter

In our Celebrity Tweets of the Week, Ellen goes to bed before dark, Conan O’Brien plays seismologist, John Stamos caught someone playing fast and loose with Photoshop, Diddy got nostalgic, jokes about the new Pope abounded -- and a whole lot more.

Charlie Sheen's inner warlock once again emerged when his 9-year-old daughter Sam became the target of bullying. So he did what any parent would do and called upon his over 9 million Twitter followers to get their finest rotten eggs, toilet paper and dog crap and vandalize his little girl's school. Sounds reasonable.

In our Celebrity Tweets of the Week, Justin Bieber had a platitude, Kelly Osbourne showed us the aftermath of a medical incident, part of the ‘Modern Family’ cast got stuck in an elevator, John Krasinski mourned the end of ‘The Office,’ Hank Azaria shared the Homer Shake -- and a whole lot more.

Miley Cyrus' claims that she and fiance Liam Hemsworth aren't on the rocks are getting harder and harder to believe. Especially when she goes out in public without her engagement ring after rumors flew recently that her husband-to-be cheated on her with January Jones at an Oscar party.

As you've most likely heard by now, Justin Bieber had the “worst birthday.” Except, you know, he didn't. But it turns out his ex-girlfriend Selena Gomez might have made that birthday suck even more when he texted her in the hopes she'd cheer him up and she completely refused to respond. Then she stroked the fluffy white cat on her lap and launched a rocket into the moon while yelling "TAKE TH

The saga of the Broadway play on which Shia LaBeouf bailed continues, as Alec Baldwin, hurt that LaBeouf would share his private emails, fires back -- and LaBeouf returns fire by making even more personal notes public. It's like our own little celebrity version of WikiLeaks.

Olivia Wilde bravely went where many dare not dwell (except for Patrick Carney, who seems to enjoy igniting the ire of teenage fan bases) by insulting Justin Bieber on the interwebs. This, of course, prompted Beliebers the world over to fetch their torches and pitchforks in defense of their demigod.

We love having fun with Alec Baldwin because it’s clear he’s a fun-loving guy. For all the hits he takes in the media, he's never lost his sense of humor. That’s why, when we see on his Twitter page that he’s had some sort of accident, we’re at first concerned -- and then we wonder what sort of shenanigans he might be up to.

Donald Trump, who has his share of detractors thanks to public stunts like asking President Obama to prove his citizenship and suing comedian Bill Maher for cracking jokes about him, was so happy that someone actually complimented him on Twitter for once that he went right ahead and retweeted the seemingly innocuous statement without giving it a second thought. At least until someone pointed out t

It’s the best thing to hit the internet since Grumpy Cat: Video editing geniuses -- also known as people with a lot of spare time on their hands -- cut clips of screaming goats into the long notes of loud and well-known chick anthems and other pop hits. Scores of songs have been thusly "honored." But how do the people who recorded the originals feel about it? We can't speak for everyone

In our Celebrity Tweets of the Week, Charlie Sheen showed us why he wasn't at the Oscars, Russell Crowe may have celebrated a bit too much after the show, Kevin Smith laid to rest rumors of ‘Clerks III’ casting, Rob Lowe weighed in on Dennis Rodman’s visit to North Korea -- and a whole lot more.

Despite no longer being married, Denise Richards still likes to nag Charlie Sheen on Twitter as if they were. And exchanges like this make it clear he should've never let her go.

Apparently you can touch this -- at least if you're a cop. MC Hammer (real name: Stanley Kirk Burrell) was arrested on Thursday, Feb. 21 in Dublin, Calif., on suspicion of obstructing an officer in the performance of their duties and resisting an officer. But he says it was a case of racial profiling.

In our Celebrity Tweets of the Week, Kelly Clarkson and Clive Davis had a little dust up, Lady Gaga had a message for her Little Monsters before she had surgery, Don Cheadle wants to be Sarah Silverman’s hero, Rita Wilson and Tom Hanks looked utterly adorable together on their first Oscars date -- and a whole lot more.

Blowhard billionaire Donald Trump generally uses his Twitter account to complain about the state of the world, which is why everyone was confused when he seemingly posted a “raunchy” Lil Wayne lyric from will.i.am. and Britney Spears' remix version of 'Scream & Shout' instead of announcing his latest ridiculous lawsuit.

One Direction member Liam Payne still can't seem to understand that not everyone knows who he is. He threw a hissy fit online back in December because the Empire State Building wasn't aware of his existence, and now he's attacking Boy George, who mistook him for his bandmate Niall Horan at the 2013 Brit Awards.

Shia LaBeouf recently walked out of what was going to be his Broadway debut, a play called 'Orphans' co-starring Alec Baldwin. While producers say he left due to “creative differences,” LaBeouf is painting a different picture on Twitter, trying to prove through email screenshots that ... well, we're not entirely sure what he's trying to prove here.

Five months after she left to undergo treatment for MDS, a dangerous bone and blood marrow disease that required her to get a bone marrow transplant, 'Good Morning America' anchor Robin Roberts returned to the daytime news show this morning (Feb. 20) -- and celebs and other luminaries had a warm welcome for her.

Everyone’s losing their ish because off-color comedian Lisa Lampanelli tweeted the n-word along with a pic of her and Lena Dunham. Are we shocked? It’s Lisa. This is what she does to make us think she’s still worth talking about.

Remember how Alec Baldwin used a bunch of racial slurs against a New York Post photographer and threatened to choke one of their reporters to death? Neither does he -- because apparently it never happened.
