"We know what you ate this summer, Love – everything!" TMZ.com notoriously wrote.
Now, the Ghost Whisperer star has the last laugh.
In the new issue of Us Weekly, on newsstands now, the 32-year-old shows off the new body she got after just 10 weeks and her trainer reveals to Us exclusively how she lost 18 pounds.
"I am in a pretty good workout regimen that I like, so it inspired me to keep it up," Hewitt tells Us. "The energy level and the way I feel now is great."
"With her, it's not, 'I want to look good in that dress,'" trainer Stevie Sant'Angelo tells Us. "She wanted to start moving around because she thought it would make her feel better.
"She told me, 'They said some rude, mean things, but that's not why I wanted to change,'" Sant'Angelo says.
