Mark Zuckerberg is known for a lot of things — starting Facebook, inspiring the Aaron Sorkin-David Fincher movie The Social Network — but fashion is not one of them.

The CEO and co-founder of the social networking giant has been ranked the worst dressed man of Silicon valley according to a new poll by GQ. The news comes less than a year after he was named to Esquire’s worst-dressed list in January.

Zuckerberg’s “style sins” include that he’s “oblivious to the fact that jeans and ties come in skinny sizes—or that suits exist” and that “he loves to recycle the fresh-from-Stats-class look. Zuck’s style is so poor, it even inspired a mock fashion line, Mark By Mark Zuckerberg, which thankfully doesn’t sell any actual clothing.”

Apple CEO Steve Jobs, who favors a uniform of a black mock turtleneck and jeans, comes in at No. 2.

“Apple releases an iPhone every 0.5 seconds. Steve Jobs never gets an upgrade. The Svengali’s self-inflicted uniform (black turtleneck, dad jeans, Seinfeld kicks) rival Superman’s in its homogeneity—a style blunder no AutoCorrect can fix,” writes GQ.

Bill Gates ranks No. 3.

“Curious how Harry Potter will age post-Hogwarts?” snipes GQ. “When you’re Scrooge McDuck rich, a snazzy ensemble isn’t tops on your to-do. Rather than swag out in Armani suits, Gates takes the lazy preppy approach, opting for a drawer full of V-necks in every hue.”

A planned Michael Jackson tribute concert, supported by the late pop star’s mother and four siblings, was in disarray Thursday.

Tickets for the show, scheduled for Cardiff, Wales, in October, were to go on sale Thursday, but instead of providing a link for purchases the promoter’s website asked fans to “Please Standby for further announcements.”

The head of the British company promoting the concert promised last week it would “feature the world’s most amazing music performers.” The roster would be revealed online one act at a time over the next 10 days weeks, Global Live Events CEO Chris Hunt told reporters at a July 25 news conference.

“Everybody’s in the midst of signing contracts so nothing can be announced until that happens,” Juliette Harris, spokeswoman for Global Live Events said late Tuesday. She suggested an announcement would come Wednesday.

By Thursday, still no acts had been announced.

The problems started soon after brothers Marlon, Tito and Jackie, sister La Toya and family matriarch Katherine Jackson attended the “Michael Forever: The Tribute Concert” announcement at the Beverly Hills Hotel on July 25.

But Jermaine and Randy Jackson, the only brothers not at the news conference, issued a sharply worded statement that reflected a deep division within the Jackson family over the show.

“We want to make clear that this does not reflect the position of the entire family,” the two brothers said in a joint statement.

“While we wholeheartedly support the spirit of a tribute that honors our brother, we find it impossible to support an event that is due to take place during the criminal trial surrounding Michael’s death.”

The Michael Jackson Fan Club agreed with the two brothers, issuing a similar statement.

Jackson fans posted messages on the concert’s Facebook page questioning ticket prices and the process for buying them.

Fans must place bids for a chance to buy a ticket. The higher their pledge to a charity, the better their chances of getting a good seat.

“The ticket system is so bad!! the higher you bid the better seats you get?? not every Michael fan is rich!!!” one fan posted on the “Michael Forever Tribute” Facebook page Thursday.

After several days of such negative posts, a link to the Facebook page was removed from the concert’s website.

Picture 1: The 19-year-old Wizards of Waverly Place star (and Justin Bieber’s best girl) works some fashion magic, loving simple, fresh pieces like patterned tops and cute shorts ensembles. Her slinky style is so in demand that she now designs a line for Kmart called Dream Out Loud.

Picture 2: A breakout style star during awards season – when she was nominated for her role in True Grit – the 14-year-old actress stunned in dresses from big-league designers like Marchesa and Prada. She continues to take fashion risks, from stylish suits to bold prints, and her commitment to fashion earned her the Miu Miu Fall/Winter campaign. The collaboration, she says, “feels appropriate”.

Picture 3: She’s worn a homecoming dress and a cap and gown, and the 17-year-old star’s all-American style doesn’t stop once she leaves high school and hits the red carpet. She’s a fan of laid-back denim looks and romantic gowns – but she’s not afraid to show her wild side in ads for Marc Jacobs’s Oh, Lola fragrance.

Picture 4: Dakota’s 13-year-old sibling (and star of this summer’s Super 8) may be a few years behind her big sister, but she looks like she’s been hitting red carpets for years, choosing risky styles and posing like a fashion pro. After stepping out in ensembles from lines like Valentino and Chanel Haute Couture, the young star was tapped by Marc by Marc Jacobs to be the face of its Fall ad campaign.

Picture 5: The star of Nickelodeon’s Victorious, 18, digs classically pretty attire – picking pieces that are feminine and flirty without being over the top. The actress and singer knows what she likes – from her favorite loose waves to the high hemlines on her bold-colored frocks, she’s got a definitive style and loves to stick to it.

Picuter 6: The Kick-Ass star’s style is, well, just that: Though young, she is not afraid to take chances with her films or her wardrobe. From ladylike patterned dresses to a superhip hat-and-jumpsuit outfit, the 14-year-old has the red carpet confidence of an actress twice her age.

Fans can experience the “glitz, glamour and romance” of Kim Kardashian’s marriage to Kris Humphries in a two-part television special on E!, the network said Wednesday.

“Follow the bride, groom and entire Kardashian clan every step of the way, from the lavish wedding planning to the fabulous parties to the highly anticipated big day when Kim and Kris say ‘I do,'” a statement read.

Kardashian, 30, got engaged to the New Jersey Nets player, 26, in May and the pair will marry Aug. 20.

The bride-to-be revealed this week she will wear a wedding dress created by family friend and celebrated designer Vera Wang for her “wedding extravaganza.”

“Kim’s Fairytale Wedding: A Kardashian Event” will air Oct. 9 and 10 on E!, which is also home to the starlet’s hit reality show “Keeping Up with the Kardashians.”

Supermodel, Thailand tsunami survivor and former “Dancing With The Stars” contestant Petra Nemcova sat down with the Telegraph to talk about her charity, the Happy Hearts Fund, which helps countries rebuild after natural disasters when the first responders leave. Nemcova mentioned that in the last five years, Happy Hearts has reconstructed 51 schools and has a presence in nine countries.

She also discussed her upcoming wedding to British actor Jamie Bellman, explaining, “We met through a neutral friend, well, his best friend since he was ten, so for twenty years — and he’s now engaged to my best friend who I’ve known for seven years. And they brought us together and so it’s stayed in the family, which is wonderful.”

Deets, girl, deets! Petra added, “In terms of the wedding and the preparation, there are some things set in stone, like the date, which will be in June 2012, and the wedding will be in England, since we both love England. It will be in the countryside. The wedding dress will be designed by Marchesa. The relationship with Marchesa, for me, has been for many, many years. It’s just nice to be able to wear them even on that special day. And I can’t wait to see what they will create.”
