That's why Diet Coke and actress Minka Kelly are blending fashionable style and the power of expression to support The Heart Truth ®campaign, led by the National Heart, Lung, and Blood Institute (NHLBI). With a social media-inspired package at the center of this year's campaign, Diet Coke will help raise awareness and ignite a digital conversation around The Heart Truth ®.

The hashtag encourages Diet Coke fans to upload and share heart-inspired photos representing what "showing your heart" means to them. Throughout the month of February, each photo tagged on Twitter and Instagram with #ShowYourHeart will trigger a $1 donation from Diet Coke to the Foundation for the National Institutes of Health (up to $100,000) in support of women's heart health research programs. "Through the power of our fans, Diet Coke can raise awareness and support for The Heart Truth® campaign," Erik Jenkins, Diet Coke Brand Manager. "We hope every time someone picks up a Diet Coke can and sees the striking brushstroke heart design, they'll use the hashtag to join the social conversation supporting this important cause." Diet Coke will take the message from the can to the catwalk at the annual Red Dress CollectionSM Fashion Show on February 6 at the Hammerstein Ballroom in New York City. Actress Minka Kelly will walk in the show as Diet Coke's Celebrity Ambassador. Her red gown, designed by Oscar de la Renta, will remind women to raise awareness for this important cause. "Every woman can play an active role in her heart health, but many may not realize it," said Minka Kelly. "I'm so excited to be a part of a campaign that brings attention to this important issue, and have the opportunity to inspire other women to get involved." Joining Minka Kelly at the Red Dress CollectionSM Fashion Show will be five lucky Diet Coke fans that entered a photo-sharing contest and won a trip to the star-studded event. These fans uploaded heart-inspired photos with the #ShowYourHeart hashtag and were selected by Diet Coke.
