Underwood, a longtime animal lover who used to volunteer at a local veterinary clinic, recently revealed to US Weekly that when she ties the knot with hockey player, Mike Fisher, she will definitely have Ace in her ceremony.
"It would be like if I was getting married and I had a child - of course my child would be in the wedding," Underwood said.
She added that while Ace may be donning a tuxedo for the big day, he may have a little assistance with some of his ring-bearing duties.
Underwood told the news provider that Ace would not be getting the actual ring for fear that the small dog would run off with it or even accidently swallow it—compromising her pet’s health.
Underwood, who is rarely seen without Ace, is excited to make him a part of her ceremony.
"He's like my kid," she said.
