Keith Urban subtly addressed his split from Nicole Kidman before their divorce news went public. Resurfaced video footage from one of Urban's recent concerts showed the singer changing the lyrics in his song "The Fighter," which features Carrie Underwood. "When they're tryna get to you, baby, I'll be the fighter," Urban, 57, usually sings. However, he instead offered a shout-out to his guitarist and rising country music star Maggie Baugh, according to a video shared via Instagram on Saturday, September 27.
