They are always up to something fun, and on Monday night (May 6) Kate Upton and Leslie Mann showed up for the 2013 Costume Institute Gala in New York City.

The “Other Woman” pals looked gorgeous in their colorful frocks as they posed together on then arrivals carpet in front of the Metropolitan Museum of Art.

Every year, the Costume Institute of The Metropolitan Museum of Art puts together a killer collection of amazing goodies complete with a star-studded party to kick things off.

And this time around the theme is “PUNK: Chaos to Couture,” an examination of punk’s impact on high fashion from the 1970s up to the collections found on today’s runways the world over.
