The mini-mogul, now 23, had been slated to play glamorous teen socialite Schuyler van Allen on The CW Network’s adaptation of the young adult literary series Blue Bloods, according to GLOBE. Blue Bloods creator Melissa de la Cruz selected the “cool and vunerable” Mary-Kate for the role. However, Mary-Kate’s big vamp debut fell through when the network dumped the pilot in favor of another show about immortal high schools — The Vampire Diaries.

Word is CW bosses dumped Mary-Kate’s starring vehicle after deeming the show “too similar to Gossip Girl.”

The sisters have been recognized by the exclusive organization for their contributions to American fashion through their labels, The Row and the Elizabeth and James collection, named after their younger brother and sister.

Mary Kate & Ashley will join fellow big name designers Alexander Wang, Jason Wu, and Maria Pinto when they are welcomed as new members of the CFDA in a dinner at Manhattan’s Four Seasons Restaurant on October 21, British Elle announced Tuesday.

Acclaimed designer Diane von Furstenberg, who is CFDA President, will host the affair.

The 22-year-old twins shared the part of “Michelle” on the hit series from nine months old to age 8.

“Full House is on all the time. Really. I see that it’s on. But last year, Ashley spent the night at my place and I woke up to the theme song at seven in the morning,” MK reveals in the March issue of Interview.

She also revealed Full House producers used bribery to get a young Mary-Kate and Ashley to complete their scenes.

“We would get little gummy bears – like a gummy bear cut into three pieces. And we’d crawl to the gummy bear or reach for it. The outtakes of Full House are pretty funny.”

“We basically learned how to talk in front of the cameras by copying somebody else’s words or movements.”

The Hollywood Walk of Fame stars of actresses Sharon Stone andd Mary-Kate and Ashley Olsen were defaced and smudged with the words “FUR HAGS!” by anti-fur campaigners over the weekend.

Activists supporting animal rights group People for the Ethical Treatment of Animals (PETA) have made a campaign of routinely discouraging the use of fur and protesting against the torture inflicted on animals as part of the fur trade.

Animal rights activists’ favorite fur-wearing celebrity sibs are seeking to expand their literary franchise with the publication of a new book for kids.

With their coffee table book Influence flying off the shelves of booksellers’ across America, Mary-Kate and Ashley Olsen have decided to once again put on their author caps and pen another national bestseller.

The mini-moguls are diligently working on their first children’s book, based on none other than the subject they know best-twins!

“Mary-Kate is doing the illustrations, while Ashley is coming up with the story,” a friend reveals to Star. “They’re hoping to do an entire series based on this concept.”

An all-out celebrity girl fight has broken after between Kirsten Dunst and Mary-Kate Olsen, after the actresses were spotted exchanging unpleasantries during a wild night out in Miami’s South Beach last week.

The girls, who were in town for THE Art Basel Convention, reportedly got into a nasty spat while sitting together at The Audi Party at the Delano in South Beach last Wednesday night.

“They just kind of stared at each other for a long time and then started exchanging nasty words,” says an onlooker. “Then Olsen just got up and left. She’s been going really late every night.”

Mary-Kate Olsen begins her guest stint on Samantha Who? this Monday, November 10.

One-half of the world-famous Olsen Twins will play bad girl named “Natalie,” who is befriended by Samantha after being sentenced to community service, on the popular ABC series.

Mary-Kate and Ashley Olsen join 23 other famous faces, including Kate Hudson, Cindy Crawford, Denise Richards, Elisha Cuthbert, Felicity Huffman, Salma Hayek, and Susan Sarandon, as vintage pin-up girls in the Timothy White’s new photography book, Hollywood Pinups.

Big things are about to start popping for the Olsen Twins.

The 22-year-old entertainment titans, who have been plagued by rumors of strife in recent months, have found something new to argue over–surgically expanding their bust lines!

Mary-Kate was left horrified, says a Star Magazine mole, after her sister Ashley suggested the former child stars purchase matching chest muscles.

“Ashley is considering getting her boobs done because she wants to look more voluptuous,” one Star snitch giggles, “and she told Mary-Kate that she wanted her to get one at the same time so that it wouldn’t be glaringly obvious that Ashley had work done.”

“That way, they could say that they had just both matured and were filling out naturally.”

Sorry Ash, it doesn’t sound like MK is in a Nip/Tuck kind of mood.

“She told Ashley no way! Mary-Kate hates being told what to do and how to look by Ashley. It drives her nuts. Anyway, she’s into that flat look and thinks clothes look better with less cleavage, so she’d rather be smaller and more stylish.”
