Watching 'Fireflies...' makes Roberts emotional

London,  - Actress Julia Roberts became emotional while watching “Fireflies in the Garden” as it brings back memories of her pregnancy.

The 43-year-old was pregnant with her son Henry when she filmed the movie in 2007.

"When I see it now, he's this big boy who can dress himself and do all these things. It really is touching to see that. I think motherhood is challenging for everybody in different ways," femalefirst.co.uk quoted Roberts, who is married to Danny Moderalso and also has seven-year-old twins Hazel and Phinnaeus, as saying.

"My challenges as a wife and a mother are very different from the ones portrayed in the movie, but I think for everybody it's a hard challenge."
