The 2015 Met Gala has only officially begun, but there's a clear leader in the race for best couple, no small feat at an event that threatens to sap Hollywood of every celebrity it has for the duration of an East Coast evening.

That would be Marc Jacobs and his surprise guest (who, by some miracle, remained under wraps until their red carpet debut), Cher.

“This has been a dream of mine for a very, very long time,” Mr. Jacobs said.

It is Cher's first appearance at the Met Gala since 1997, when she arrived on the arm of Donatella Versace.
