The "Cry Pretty" singer and her husband Mike Fisher arrived at the Academy of Country Music Awards, which are being held at the MGM Grand Garden Arena in Las Vegas, looking stunning in a diamond embroidered Nicolas Jebran dress that was one-shoulder and had thigh-high slits.
Underwood's presence at the show marks her first red carpet appearance since giving birth to her son Jacob Bryan Fisher on January 21. She announced the news on Instagram and shared photos of her husband Mike Fisher as well as her other son Isaiah Michael Fisher holding his new brother.
"Jacob Bryan Fisher entered the world in the wee hours of the morning on Monday...his mom, dad and big brother couldn't be happier for God to trust them with taking care of this little miracle!" she captioned the images. "Our hearts are full, our eyes are tired and our lives are forever changed. Life is good..."
Underwood told E! News at the ACM Awards that Isaiah is a huge fan of being a big sibling.
