It was a big night for Miranda Lambert
and Blake Shelton
The couple took home individual honors at the Country Music Association Awards Thursday night – including an entertainer of the year honor for Shelton! – but the most emotional moment came when they accepted the award for song of the year for their powerful duet, "Over You."
"I lost my brother in a car wreck when I was 14-years-old, and later in life when I decided I wanted to be a country singer, my dad always told me, 'Son, you should write a song about your brother,' " Shelton said alongside his wife
"I lost my dad in January, and it's so amazing to me that tonight even after he's gone, he's still right," he continued as the audience cheered and Lambert fought back tears.
"I just needed the right person to write this song with and the right person to sing it," Shelton said to his wife. "I love you so much, baby," he added as he kissed Lambert's forehead.
Then it was a tearful Lambert's turn to take the mic.
"Thank you, Blake, for allowing me to sing this beautiful song and write it with you," she said. "Thank you CMA and all of our peers for voting for us. It's really emotional. We love y'all."
Later in the evening, Shelton took home the award for male vocalist of the year for the third time and ultimately, entertainer of the year.
"I'm gonna be totally honest, I've had a few drinks since the song of the year announcement and I was actually sitting there thinking either Jason [Aldean] or Luke [Bryan] had this one," he said.
Shortly after, Lambert followed suit, winning female vocalist of the year for the third time.
"Holy crap! I don't necessarily deserve this but I'll sure take it," she said.
Equally surprised was Shelton when he took top entertainer honors: "I'm still Willied out here. I didn't even go to change!"
