Gwen Stefani Shares Photo From State Dinner

The star performed in front of the Obamas and the PM of Italy.

Renzi later shared the group photo on Facebook.

Stefani's big moment came after dinner, when she took the stage to perform some of her solo hits. She then invited Shelton, 40, on stage for a performance of their duet "Go Ahead and Break My Heart."

When the set was over, the president shook Stefani's hand and she beamed.
