Jennifer Lopez says it was a "special experience" working with her two-year-old twins on a Gucci photo shoot.
The singer-and-actress appears alongside Max and Emme in the Italian fashion house's campaign for their new children's line and says it was a joy posing with them
She told Us Weekly magazine: "It's the first time I have worked with my kids in that way. It was a totally special experience.
"I did a photo shoot when they were three weeks old, but now that they are two-and-a-half, it's totally different!"
Jennifer admits she and husband Marc Anthony weren't too keen on the tots doing it, but changed their minds because it was for a good cause - Gucci donated $1 million to UNICEF's Schools for Africa initiative and $50,000 to her charity the Maribel Initiative, which promotes greater access to health care for women and children worldwide.
She said: "It's exactly why I'm excited to be a part of this. Now there are two Gucci spokesbabies for a beautiful cause!"
The 41-year-old beauty also said little Emme is already showing signs of following in her mother's fashionable footsteps.
She revealed: "Emme picks out her own outfits and likes to sleep in her princess dress. It's hard to get Max dressed. He prefers to run around the house with no clothes on."
