These days we are more used to seeing starlets falling out of cars sans underwear but class act Emma Watson wasn’t left red-faced (or red-cheeked) when she had a wardrobe malfunction on Tuesday.

Talking on the David Letterman show last night Emma was confronted with a picture of her adjusting the vintage Ossie Clark dress she wore to the London premiere for Harry Potter and the Half-Blood Prince…

In the shot she reveals a little more than she intended and her knickers are clearly on display.

But the 19-year-old beauty laughed off her ‘wardrobe malfunction’, saying ‘At least I’m wearing underwear!‘ and blamed the mistake on her youth. ‘I’m still learning, I’m still learning!‘ she exclaimed while burying her head in her hands in embarrassment. Ah, how sweet…

Emma’s got an amazing sense of style and it’s not often we read about a child star who has manners, a sense of humour and the sense to know that going out in public without underwear is just asking for trouble. A perfect ambassador for the British abroad I think… Lily Allen take note!
