A couple of weeks ago I read an article about how celebrities offering condolences on Twitter was a little too much and should probably be kept in private. This was brought into the spotlight when Amanda Holden lost her baby and all her celeb friends were quick to tweet her to say how sorry they were. To be honest, these days Twitter is just as personal as a text message or an email, so what’s wrong with sending messages that way? However, the thing that celebs have to remember it that with Twitter, everyone can see what you’re up to (something Russell Brand and Katy Perry know all too well).

Apparently Rihanna and Ciara have forgotten that little piece of additional information though, as they took to Twitter this week and had quite a public row. Apparently Ciara was on some TV show called Fashion Police (I know right? It sounds amazing) and dissed Rihanna by saying “she wasn’t the nicest”. Bad times for Rihanna. But it’s all good, because she took the 15 year old girl approach and jumped straight on to Twitter. While she didn’t mention Ciara directly in her first couple of tweets, Ciara was obviously reading them as she tweeted back.

They basically slagged each other off back and forth for two or three tweets before Rihanna begged for them to make up, claiming she was just “heartbroken” over what Ciara had said. So apparently they made up…or at least it looks like they did.

Maybe next time the girls have a falling out they’ll think twice about where they do it, and maybe keep it hidden from the media. Saying that, Rihanna hasn’t deleted any of the mentioned tweets, so she clearly doesn’t care too much.

Popular Twitter feed,’Sh*t My Dad Says‘ is to become a TV sitcom, with William Shatner playing the titular dad.

The feed was launched in August 2009 by 29-year old Justin Halpern who used Twitter to post the bizarre musings of his elderly father. The stream now has more than one million followers and landed Justin a book deal, as well as an offer to write a TV pilot.

Financed by CBS, the pilot script has been put together by Justin with the help of Patrick Schumacker will be executive produced by Will& Grace creators David Kohan and Max Mutchnick.

Twitter has also illustrated the scale of the shock and sadness being felt by many around the world. Mashable.com has reported that Twist, the Twitter tracking tool, is showing that 22.61% of Tweets currently contain the name “Michael” while at least 30% of Tweets are remarking on Jackson’s death.

Celebrities as well as fans have also been using Twitter to express their sadness with MC Hammer tweeting “I will be mourning my friend, brother, mentor and inspiration.” Actors Lindsay Lohan and Ashton Kutcher as well as songwriter John Mayer also commented.

Following the death of the singer, Twitter was also home to some childish bickering between Fall Out Boy bassist, Pete Wentz, and Perez Hilton, the infamous peddler of Hollywood gossip. Hilton wrote a blog post which contained a picture of the singer and a caption reading “Heart attack or cold feet?” and went on to speculate that Jackson’s collapse was a stunt to get the singer out of his proposed upcoming tour. The blog was immediately changed following confirmation of the singer’s death, and Hilton was first to criticise comedienne Sarah Silverman after she tweeted an ill timed joke. Pete Wentz, his wife Ashlee Simpson-Wentz and thousands of Twitter users lambasted Hilton for his initial blog post and subsequent about face. The virtual fight escalated to a war of words between Pete Wentz and Perez Hilton with Ashlee Simpson-Wentz and John Mayer cheering from the sidelines. However, mere hours after the argument erupted everyone seemed to have made up, with apologies being issued by all involved.

The death of Michael Jackson has been a shock to his fans and peers alike and, whatever individual opinions people have of Jackson, his status as a musical legend cannot be denied.
