"I have a boyfriend, and if I'm being completely honest, no one likes to be not toned when you are dating someone," the singer confessed in a recent interview with People.
Clarkson is dating Brandon Blackstock, her manager's son, and the two share a personal trainer. Consequently, she's been eating healthier and working out more, and while her weight still rises and falls within a 20-pound range, she says that's been the case her entire life.
"I tone whenever I want, and I chose to now because my boyfriend and I are both really into it," she says.
While she and Blackstock enjoy spending time together, Kelly says they're more likely to indulge their mutual passion for music and go to concerts together than they are go to make tandem trips to the gym.
"We did that once and I didn't like huffing and puffing," she continues. "I didn't like looking all red and gross, so I don't do that."
