Another day, another wardrobe malfunction for Britney Spears.

The former 'X Factor' judge was watching her sons play soccer on Sunday in Los Angeles, when her very short sundress was blown up by a gust of wind. And because the singer wasn't wearing full underwear, her bare butt was exposed for all to see (even as she tried (unsuccessfully) to cover up).

Despite the embarrassing display of her derrière, Spears looked happy and relaxed, pairing her white dress with fur boots and large aviator shades. She also pulled her new brown locks into a trendy messy bun.

This isn't the first time Britney has suffered a wardrobe malfunction: the newly-single 31-year-old has a habit of forgetting her underpants .
