Actress Amber Riley arrives at the 43rd NAACP Image Awards held at The Shrine Auditorium on Feb. 17, 2012 in Los Angeles

*Photos of “Glee’s” Amber Riley at the NAACP Image Awards on Feb. 17, show a little less of the actress than before.

“I dropped two dress sizes!” she told People, about her new, slimmer figure – the result of a diet and exercise plan she has been following since last summer.

She cut out fast foods and “decided I was going to make a change and eat healthier.”

The actress started her regimen in July, after she was forced to see a doctor due to chronic stomach pains.

The seven-month health kick has obviously paid off. Riley says the costume department on set has had to tailor a lot of her pants and dresses to accommodate her slimmer frame. They’ve also had to buy “a lot of new clothes for me.”

Even before losing weight, the Los Angeles-born actress considered herself a confident woman. “I’ve always been comfortable with my size,” says Riley. “I just decided it was time to get healthy.”
