One of the big GRAMMYs moments came towards the end of Sunday night's show.
Thirty-four couples were married in the theatre during Macklemore and Ryan Lewis performing "Same Love".
The couples were straight, same-sex, interracial young and old.
Just hours before the show began, one of the soon-to-be newlyweds spoke to CBS5 about the experience.
Brittany Pennington and Sally Beaver met at Desert Ridge High School in Mesa. The couple has been together almost three years and they now have a wedding story that will wow people the rest of their lives.
"I'm so nervous, " Pennington told CBS5 with a laugh. "We haven't been able to eat or sleep."
The couple was invited to take part on the group wedding after responding to a very vague casting call several months back.
It was only a few weeks ago that they found out that casting call was for music's biggest night of the year.
"Paul McCartney, Katy Perry, Pink are all sitting next to where we'll be standing. So we're nervous but excited," Pennington said.
The couple lives in Seattle now where gay marriage is legal. She tells us it's huge that the GRAMMYs are being so openly supportive of equality.
"It's just so overwhelming because I feel this is gonna be a huge historic show that people will remember forever," said Pennington.
