Kelly Clarkson Weight Loss
Clarkson dropped the excess weight over the course of the past six months, with a source saying she “feels better about herself than she ever has.”
The singer, who remains 10 pounds shy of her goal weight, says that her boyfriend Brandon Blackstock helped inspire her to get back into shape.
“Brandon is the first guy ever who tells her how beautiful and sexy she is. She wants to look good for him,” a source told the celeb news publication.
Whatever her motivation, she looks outstanding.
