The country star made her first public appearance at the US TV network's annual prize-giving since giving birth to her first child, son Isaiah, in February , and her return proved triumphant, as she earned three awards, including Video of the Year for Something in the Water, reported E! online.
Upon winning her second honour for Female Video of the Year for the same video, Underwood said, "This is my first show since little Isaiah has been in the world. He's probably napping on the bus right now, but I should definitely say that he has already inspired me so much, as well as my husband Mike (Fisher). Thank you guys!"
Meanwhile, Luke Bryan claimed Male Video of the Year for "Play It Again", Lady Antebellum earned Group Video of the Year for "Bartender", and Florida Georgia Line scored the Duo Video of the Year accolade for "Dirt".
Newcomer Sam Hunt won Breakthrough Video of the Year for his track "Leave the Night On", while CMT Performance of the Year went to Bob Seger and Jason Aldean for "Turn the Page from CMT Crossroads: Bob Seger and Jason Aldean".
The event was co-hosted by "Pitch Perfect" actress Brittany Snow and US TV personality Erin Andrews and held at the Bridgestone Arena in Nashville, Tennessee.
