The White House is celebrating Italy next week at a state dinner and chef Mario Batali and singer Gwen Stefani will headline the celebration. This will most likely be the final state dinner hosted by the Obamas. The special guests were announced by First Lady Michelle Obama on Wednesday via Snapchat. Italian Prime Minister Matteo Renzi and his wife will be honored at the dinner. Batali will help prepare the state dinner and Stefani will perform the guests after they eat.
