The last time she hinted at a performance was last week when she shared another shot of herself during rehearsals. "#CryPretty #ACMAwards", Underwood captioned the photo. The 35-year-old country singer appeared to have a lineup beneath her brow.
So far, it's the third photo the Checotah, Oklahoma native has released since she fell down the steps outside of her home last November.
"First off, bodily, I'm doing fairly darn good today!" In the post, she writes of working with writer/producer David Garcia - who's worked both with Christian country artists as well as Florida Georgia Line - and said he's co-producing her forthcoming album with her. At the Billboard Music Awards in 2014, she performed "Something Bad" with Miranda Lambert and looked beyond fierce in her skintight, black leather shorts which she paired with a leather jacket and dark makeup.
Another winter storm set to slam this area
Winter Storm Xanto is also impacting travel, with top airlines in the United States waiving changes fees for impacted travelers. A snowstorm that will likely arrive in the area Sunday could result in more than 10 inches of snow falling locally.
Underwood also said that her face is healing nicely, and she feels more like herself than she has before, presumably since November previous year when she fell down a flight of stairs. A number of followers commented on the photograph and speculated it was a scar from her disastrous fall. My wrist is sort of again to regular, about 90% there...and the docs say that final 10% will are available in time. I know it's been a big story, but I think, I'm sure she'll be relieved to finally move on from all that stuff too. "I definitely feel more like myself than I have in a while". It means I've already been to support my favourite hockey player appearing out of retirement! "But, listen, Carrie Underwood's going to be as lovely as ever".
The song she'll perform at the show is "Cry Pretty", the first track from her forthcoming, still-untitled album. McEntire is a 16-time ACM award victor, and she's among the singers competing for Female Vocalist of the Year.
