Braless Halle Berry, twerking Gisele and gyrating Emily Ratajkowski lead the stars letting loose on the dancefloor as new photos reveal what REALLY goes on inside the Met Gala

On Monday evening stars swept the famous steps outside the Metropolitan Museum of Art at the heart on New York's 5th Avenue for the annual star-studded Met Gala. And after ensuring they showed off their glamorous gowns in all their glory on the red carpet, it was time to let loose as they headed into the exclusive event. Straight onto the dancefloor, Halle Berry wasted no time showing off her signature moves, joining Celine Dion as they threw their arms up in the air, no doubt inspiring models Gisele and Emily Ratajkowski who were quick to follow in their footsteps.
