Los Angeles: Actor Hilary Duff has called out online trolls for criticising her body. 

The mother of two fired back at the body shamers while proudly showing her "flaws" in a bathing suit after many posted nasty comments about her body during her recent Hawaii holiday, reported Ace Showbiz. 

"I am posting this on behalf of young girls, women, and mothers of all ages. I'm enjoying a vacation with my son after a long season of shooting and being away from him for weeks at a time over those months," she captioned a photo.

"Since websites and magazines love to share 'celeb flaws' - well I have them! My body has given me the greatest gift of my life: Luca, 5 years ago. I'm turning 30 in September and my body is healthy and gets me where I need to go."

Duff said women should be be proud of their bodies and stop wasting their precious time in the day "wishing we were different, better, and unflawed."
