Twitter

British boy bands One Direction and the Wanted have once again reignited their possibly PR-driven feud over the social media site Twitter.

Twitter hashtags only have a couple purposes: track current conversational trends, and maybe keep people informed (or distracted). But every now and then a poorly-worded phrase confuses the masses. Like Susan Boyle's anal bum party. Or, in this case, a hashtag about today's passing of former British Prime Minister Margaret Thatcher -- which oddly had Cher fans in an uproar.

In our Celebrity Tweets of the Week, the Fonz pranked Tom Bergeron, ‘Hot in Cleveland’ had an epic cast list, Jimmy Kimmel congratulated Jimmy Fallon and revealed a relationship we didn't even know they had, Demi Lovato went unmasked, the dearly-departed Roger Ebert got two thumbs up from St. Peter -- and a whole lot more.

Considering Roger Ebert's life revolved around movies, when it ended, it was tragic for the celebs he saw onscreen.

Retired millionaire, live-action art project and birthday girl Amanda Bynes missed court yesterday in her suspended license case, but was still spotted running around New York City with brand new red extensions. However, as the now 27-year-old Bynes explained on Twitter in some since-deleted messages, that girl who looks just like her -- cheek piercings, jewelry and all -- wasn't really her, but a

Amanda Bynes is still keeping her family up at night, tweeting a series of platitudes seemingly aimed at a special someone this weekend.

Rosie O'Donnell is no stranger to controversy, but an innocent tweet caused all sorts of problems for her this week.

In our Celebrity Tweets of the Week, Miley Cyrus need a hobby, Kristen Bell spawned, Tom Bergeron has a Vulcan song in his heart, Seth Meyers has an idea for a blockbuster movie, Amanda Seyfried is mistaken for someone even more famous than she is -- and a whole lot more.

It's been an eventful couple of weeks for Amanda Bynes. Her privates were nearly murdered and she might be getting pudgy, so it only makes sense that she's under a little stress. Now she's threatening to sue gossip bloggers on, uh, some legal ground she hasn't thought of yet.

Yesterday, March 26, the Supreme Court began hearing arguments both for and against Prop 8, which banned same-sex marriage in the state of California. In addition to changing their social media profile pics into the Human Rights Campaign's red equality sign, some celebrities tweeted feverishly for the repeal of the proposition, while others took to Facebook to express their support for marriage eq

Amanda Bynes has been exhibiting some strange behavior via Twitter lately, which finally has her relatives worried. (Yes, finally.) Adding the icing to an already troubled cake that had her musing about rapper Drake "murdering" her lady bits, Bynes is back to snapping poorly-taken selfies and complaining about her body.

In our Celebrity Tweets of the Week, Jose Canseco has a very famous paramour, Seth Meyers gives a history lesson, Zach Braff has a frightening proposition for Kristen Bell, Lena Dunham's purse is boobytrapped, Samantha Ronson thinks you, uh, do what you eat -- and a whole lot more.

Former Nickelodeon star Amanda Bynes has been behaving bizarrely for a while now. Earlier this week, she revealed a crush on singer Drake in her usual off-kilter way -- but her latest tweet about him was weird ... even for her.

It’s hard to believe that Twitter has been around for seven years. It’s also hard to believe that we have so much seemingly close access to celebrities because of it. (Even though Tina Fey still refuses to join. Hmph.) But even celebs' first tweets – like those first baby steps we all take – were every bit as awkward as the rest of our “Just figuring this Twitter thing out” missives. So, in honor

Yesterday, March 20, would have been the 44th wedding anniversary of Yoko Ono and John Lennon -- had he not been shot and killed in 1980 by a lunatic fan. (Like Paul McCartney, we refuse to mention Lennon's killer by name.) In commemoration of her fallen husband, the now 80-year-old Ono tweeted a photo of his bloodied glasses (which originally appeared on the cover of her 1981 album 'Season of Gl

Rumors have been swirling that country singing husband and wife duo Blake Shelton and Miranda Lambert are headed for a divorce due to Blake's wandering eyes (and hands). So the duo dealt with these blasphemies the best way they could: by mocking them on Twitter.

One of our favorite Twitter accounts is the one belonging to Amanda Bynes, because it's like an unfiltered look into her head in real time. Without the social media site, how else would we know that she's crushing on Drake when he switches mugs with Nicki Minaj and shows off his “incest face”?

Despite taking a break from social media and an even more talked-about alleged break from her fiance, Liam Hemsworth, seems Miley Cyrus is back -- and so is her engagement ring. Blatantly so.

The battle between Charlie Sheen and his daughter's former school continues, with Sheen once again sounding off on Twitter in response to what he says is bullying in response to anti-bullying -- with the victims this time being his kids and ex-wife.

For some reason (meaning "this is how these things work"), it was rumored that Emma Watson, the erstwhile Hermione Granger from the 'Harry Potter' franchise, would be taking on the lead in the film adaption of the BDSM mommy-porn bestseller 'Fifty Shades of Grey.' A rumor “confirmed” by some hackers -- something Watson herself found so hilarious that she decided to address it herself thi
