The country musician also walked the red carpet of the event with her boyfriend, Anthony "Skeeter" Lasuzzo. The relationship is McEntire's first public one since she and Narvel Blackstock finalized their divorce in October 2015.
McEntire introduced Lasuzzo as her new man in a red carpet interview with "Entertainment Tonight."
The singer hasn't been shy about her new relationship on Instagram. She shared a photo of the pair going on a hike in December, as well as stops at family celebrations over the holidays.
“We’ve been having fun!” McEntire told “ET.” “We’ve been to three plays here in New York, just enjoying it tremendously.”
The couple certainly had a busy Grammys weekend.
On Friday night, the pair watched a performance of the Broadway musical "Come From Away" and snapped a photo with the cast.
On Saturday, the couple met up backstage with singers Sara Bareilles and Jason Mraz after seeing them star in Bareilles' Broadway musical, "Waitress."
Before the Grammys, they had brunch in the city with McEntire's team.
“We like to have fun whether it’s the mountains or New York City,” McEntire said.
