Bulgari is proving that they have a big heart this Valentine’s Day — with a little help from Sex and the City heartthrob Jason Lewis and other philanthropic celebs. The exclusive jeweler is launching a limited-edition ring in honor of their 125th anniversary to benefit Save the Children‘s Rewrite the Future campaign. Ellen DeGeneres, Portia De Rossi, Hugh Jackman, Debra Messing and more stars are joining Jason in slipping on the rings and stepping in front of the camera to promote the cause. You can do your part — and look good while you’re at it — by being among the first to purchase one of the silver rings tomorrow on their Valentine’s Day launch. Each ring is engraved with the Bulgari logo on the outside with the charity’s logo inside — and $60 from the $290 purchase price of each goes directly to fund the charity’s education initiative.
