Rumer Willis showed photographers a bit more than she intended to while pausing for some red carpet pics at Elle's Women In Music event last night.
At least we think that's more than she meant to reveal. Maybe the underwear is part of the outfit. Or maybe today Rumer's enjoying the free publicity that comes with any wardrobe malfunction.
All we know for sure is that Bruce and Demi's daughter is certainly all grown up and she's making sure the whole world knows it.
Rumer's in good company, of course, as celebs accidentally baring their bathing suit bits has become something of a modern Hollywood tradition.
Rihanna suffered a wardrobe malfunction at the MTV Movie Awards earlier this month and dozens more have flashed the paps in the decade since Janet Jackson started the trend at the 2004 Super Bowl.
Rumer has received some bad press for her appearance in the past, so if this is what she needs to do to feel sexy, we say go for it.
Plus the attention can't be bad for her ailing acting career. We think Rumer may have known exactly what she was doing when she stepped out in that Fifth Element band-aid dress.
