Madonna to perform at tonight’s Grammy’s.

QUEEN LATIFAH is reportedly to perform the group marriage ceremony tonight at the Grammys, according to the New York Times. E! Entertainment also said Madonna will perform with Macklemore & Ryan Lewis.

It’s some line up.

But the producers behind the program, which is to be broadcast live by CBS at 8 p.m., are hoping that the biggest show-stopper of the night will be a much more solemn event: an on-air wedding of 34 couples “” gay, straight, old, young, of many races and many colors. The ceremony will be part of the hip-hop duo Macklemore & Ryan Lewis’s performance of their Grammy-nominated song “Same Love,” which became a marriage-equality anthem last year just as that issue was drawing intense national attention.

Stay tuned, it could be a night of weddings, celebrations, awards that makes one hell of a wedding reception for a lot of people.

“We’re serious about this,” said Ken Ehrlich, the longtime producer of the Grammys.
