Reese Witherspoon learned a very valuable lesson when she stepped out without underwear to run errands in LA.
Sporting a floaty skirt on a windy day and opting to leave her knickers at home, the 37-year-old was probably regretting that decision by the time she noticed the paps hanging around.
Casually running from meeting to meeting in the red-and-white ensemble, Reese failed to notice the back of her skirt blow up to reveal her bare buttocks to the world.
Continuing to waltz down the street, the mum-of-three looked blissfully unaware of her wardrobe malfunction - which was probably for the best.
Reese spent the rest of the day battling with the skirt, eventually realising its wayward attitude and opting to drive to the rest of her meetings.

Despite the minor faux pas (be thankful the paps were behind her), Reese was happy to smile at the waiting photographers to keep up her 'light' attitude following her arrest in April.
The actress was arrested for disorderly conduct in Georgia when she drunkenly tried to stop a policeman from arresting her husband, Jim Toth.
Footage from the arrest showed Reese lying about being pregnant and using the old 'you're about to find out who I am!' line on the officer.
She later apologised for her behaviour and has since kept a light and airy temperament in public, despite previously having a poor relationship with the paps.
