The recently slimmed-down star first showed off her incredible weight loss when she appeared on the season 4 finale of The Voice and performed with Pitbull.
Then, at a press event the following month, she showed that she's managed to keep the weight off when she strutted her stuff in a form-fitting hot pink mini dress.
Obviously, it would the logical assumption to think that she's probably been putting in some serious sweat sessions--but as it turns out, she's been anything but strict when it comes to her workouts.
"If I can squeeze in a workout, great. If not, that's OK, too," she told ABC News.
That doesn't mean she isn't getting her cardio in, though. Regarding her 5-year-old son Max, she said, "Running around with him all day is pretty good exercise."
We can imagine it would be!
One thing she has reportedly been doing is a meal delivery diet where she is having healthy meals sent straight to her door.
Whatever the sexy singer is...or isn't doing...it's working!
