Guess Which Royal Is Flashing Her Spanx?

This princess gave onlookers a little more than they bargained for when she accidentally showed off a bit of her shapewear on her way to an event

Whoops!

During a stroll to St. George's chapel at Windsor Castle in England Friday, this particular princess left little to the imagination (in the shapewear department) as she revealed a bit of her Spanx through the split of her floral pencil skirt.  

So, which young royal committed this fashion faux pas?

Princess Beatrice!

The fascinator-loving royal was on her way to a memorial service for the Queen Mother and Princess Margaret when the tights-baring incident occurred, according to the Daily Mail.

But aside from that slight wardrobe malfunction, we have to admit Beatrice looked quite chic as she walked to the church in a navy blue cropped jacket, blue pumps and a way-toned-down cream-colored cap.
