Sofia Vergara is enlisting her fans to carbo-load up on half-pound, 333-calorie meatballs for charity.

The 41-year-old actress twirled spaghetti in Buca di Beppo's cheesy 'Meatballs 4 Niños' campaign, launching at all 97 locations Wednesday.

The grinning Machete Kills star displayed her toned arms in a black sleeveless, reptilian top and matching leggings.

For every meatball dish served, $1 will be donated to St. Jude Children's Research Hospital which helps children fighting cancer and other deadly diseases.

The 'authentic' Italian chain is just the latest in Sofia's string of endorsements - CoverGirl, Diet Pepsi, K-Mart, Comcast, State Farm, Rooms To Go, and Synthroid.

The curvy Colombian - whose net worth is $35 million - even called Buca di Beppo one of her 'favourite restaurants' in the press release.

Vergara has said she considers herself 'very lucky' to not have to follow any special diet.

'I love healthy eating. I love fish, I love eating vegetables, and I love salads. But I also love desserts. So I try to eat everything but in moderation,' she told the New York Times last May.

'I try to eat healthy during the day so that when I go [out] to dinner I can kind of eat whatever I want. I don’t go too crazy during the week. But on the weekends, I completely order whatever I want. I especially love sushi and I love Middle Eastern food.'
