The singer, who shares a passion for animals and fitness, chatted with PEOPLE this week about “one last thing” …
Last time I splurged
I’m not a car person at all, but my husband [Mike Fisher] is, so we got one of the new Corvettes. It’s fun and black. We didn’t get a convertible because Mike likes to take it to the [race] track.
Last time I did a happy dance
Yesterday. I recently bought myself and all of my friends a Fitbit [fitness tracker]. When you reach your goal, it buzzes. I set my goals pretty high, so I deserved that happy dance.
Last good deed I did
I went to visit my parents a few weeks ago and spent two days cleaning out some pretty messy pens at an animal shelter, Happy Paws. It was long and grueling, but the people that run the shelter are wonderful.
Last time I blushed
I was dancing and acting silly in the box at one of my husband’s [Nashville Predators] hockey games. I didn’t realize I was being filmed until I saw the clips a day later.
