George Clooney’s gal pal, Stacy Keibler, is getting into the healthy edibles game. Keibler, who will host Lifetime’s “Supermarket Superstars,” told us, “I’m developing my own healthy snack.” Attending the Macallan Masters of Photography event at the Bowery Hotel on Wednesday, she added, “I’d really like to target something for children because I feel like that is the generation I want to try and re-educate about food and what they’re putting into their bodies.”
