Jennifer Lopez Has Rare Fashion Mishap During 'Dance Again' Tour: More Celebrities Who Have Outfit Missteps

Jennifer Lopez had a rare fashion misstep while in Melbourne, Australia on Tuesday, showing off unsightly stains on her beige trousers.

Lopez was at the event to do a photo op and promote her "Dance Again Tour," and Australia is the last leg before the tour ends on Dec. 22 in San Juan, Puerto Rico.

Lopez is not the only big name celebrity that has had a fashion mishap in recent months.

Just last week, superstar Beyonce had one of her own, as she was out supporting basketball star LeBron James, who was named Sports Illustrated's Sportsman of the Year.

While Beyonce often is the epitome of fashion, her outfit at the gala was not as flattering as the designs she has recently been posting of herself on her Tumblr site. James’ fiancé, Savannah Brimson, wore a lovely form-fitting purple Emilio Pucci dress, and Beyonce wore a rather unflattering red pantsuit that hid her body shape. Jay-Z and James looked fashion forward as both wore a tailored suit and tie.

Back in September, Kim Kardashian suffered a wardrobe malfunction on Tuesday while promoting Midori cocktails at Fred Segal in Santa Monica.

Wearing a green velvet dress, the back was clearly undone, revealing her bra, as her fastens struggled to stay put. Prior to the event, Kardashian’s mother and manager, Kris Jenner, tried to fix the back of the dress, but to no avail. At the event, which was titled, "Midori Makeover Parlour," Kardashian made sure to take pictures from the front so the malfunction was not visible.

"Modern Family" beauty also Sofia Vergara had a wardrobe malfunction just minutes before she made her way to the 2012 Emmy Awards.

Dressed in a teal cut-out Zuhair Murad gown, Vergara ripped the back zipper of the dress before her big night out. She tweeted the mishap to her followers, which revealed half of her butt as she was wearing a thong beneath the gown.

“Yes!!!! This happened 20 min before we won!!!! Jajajajja. I luv my life!!!!” Vergara wrote as a photo caption.

Fortunately for the Columbian stunner, her wardrobe team was able to fix the malfunction before the Emmy Awards red carpet.
