Just when we thought there was nothing left Lady Gaga could do to surprise us, she goes out to dinner... apparently forgetting to put her clothes on.

The Poker Face singer popped out for a bite to eat at low-key restaurant Balans in Soho, London wearing, well... nothing really.

Her lace dress, lovely as it was, was entirely see-through and her lingerie did little to hide her modesty since she was sporting a dental floss-style thong.

Of course, the prying eyes of the media meant that she had donned the oversized sunglasses and put her hand up to her face as the flashes (no pun intended) went off.

What the other guests at the restaurant thought of their fellow diner is unknown, though we're slightly concerned that she didn't at least wear some sort of coat to protect her from the British winter.

Still, it could have been worse, at least Alex Reid didn't turn up.

Lady Gaga's outfit was, of course, definitely not designed for the publicity. After all, celebrities are often caught on camera when they're not at their best...
