Emma Watson wore a stunning flesh-colored tiered dress to the red carpet premiere of "The Perks of Being a Wallflower."

Unfortunately, the dress' design proved to be more risque than intended. Watson experienced a wardrobe malfunction when the halter-style portion of her gown shifted to one side and revealed more than a side boob.

Thankfully, the entire breast wasn't exposed thanks to her wardrobe stylist who was clever enough to place a pastie over it. The 22-year-old was, however, mortified upon discovery of the near "nip slip."

Watson has been showing more of her grown side lately. The "Harry Potter" star appeared all grown up on the cover of Glamour magazine. In the accompanying photo spread, the Oxford University student sported a sexy, short pixie haircut and revealing outfits.

The British actress flashed a lace-trim bra for several shots in the magazine spread while posed in a chair, and later showed her sultry side in a school girl-inspired fashion shot, where she wore a pleated plaid skirt with sheer hosiery.

According to the New York Daily News, the British star was previously reported to be the front runner for the Anastasia Steele character in the upcoming "50 Shades of Grey" film adaptation. She was said to be "a hot favorite to be chosen by producers Mike de Luca and Dana Brunetti."

Watson denied the gossip by making the following comments in regards to a future role, according to Entertainment Weekly:

"There are so many movies you become attached to when I've literally never even received a phone call. It was the same way with 'The Girl With the Dragon Tattoo.' I haven't read the book, I haven't a read a script, nothing."

She had then gone on to defend herself further against the swirling racy movie rumors.

"The thing is I'm not going to go out there every time someone attaches me to a film to say no or release a statement," Watson said.

"The Perks of Being a Wallflower" arrives in theaters on Sept. 14.

Watson will also appear in next year's "Bling Ring," a true story about a group of high school students who broke into and robbed celebrities' homes.
