John Legend gave the world a sneak peek of his new music video for his single "All of Me" on his Twitter account and revealed his fiancée's bare breasts in the process.

Don't worry, Chrissy Teigen is all for the nudity in posted on director Nabil Elderkin's Tumblr page. She retweeted the photo on her own Twitter account to show the world it is no "big deal."

"Literally everyone has a nipple," she posted on Thursday. "Get over it."

The 27-year-old Sports Illustrated model is known for her sharp tongue and uncensored thoughts.

On E! Fashion Police, Teigen told the show's hosts that she does not wear under, and confessed she wasn't any during their live taping. "'I should have tested this...I didn't realize sitting would be this bad," Teign said referring to her lack of underway. "I just don't like it."

Teigen recently opened up to E! own Joan Rivers about her wedding plans during New York Fashion Week. Legend and Teigen have been dating since 2007 and got engaged in 2011.

"We have everything. We're starting to get jitters," Teign said. "It's happening."

According to E! News, the couple is set to wed in September. Rivers asked Teigen if she will wear underwear during her big day.

"No way," Teign said. "I don't even wear it with this sort of stuff." (referring to her dress).

The supermodel live tweeted during the fashion shows she attended, poking fun of herself for wearing her outfit incorrectly.

"Heading to the shows with my outfit on inside out pretending it's high fashion and not me being an idiot," Teigen tweeted.

"Every time I try to be fashiony I look like I'm in The Devil Wears Prada 4 - None of the same actors," she continued.
