Gwen Stefani performs during a State Dinner reception on the South Lawn of the White House in Washington on Oct. 18, 2016 in honor of Italian Prime Minister Matteo Renzi and his wife Agnese Landini hosed by President Barack Obama and first lady Michelle Obama. 

She’s not the POTUS or the FLOTUS, but for a few minutes overnight Gwen Stefani was the boss of the White House. 

Stefani and her beau Blake Shelton mingled with the VIP guests before turning-on the entertainment for President Barack Obama and First Lady Michelle Obama's final White House State Dinner.

The No Doubt singer, whose father is of Italian decent, performed at the special gathering Tuesday night (Oct. 18), which was held in honor of Italian Prime Minister Matteo Renzi and his wife Agnese Landini.  

Stefani was joined by Shelton on guitar as the pair delivered their hit collab, "Go Ahead and Break My Heart."  

Obama gave a warm welcome to the pop star who lit-up the room -- and social media -- with the performance. Before the night was done, Stefani swapped out her Twitter profile picture with a new snap of herself sharing a laugh onstage with the President. 

Later, Chance the Rapper -- one of the many artists watching on -- quipped on Twitter: “Gwen Stefani just sang to me at the White House. And pointed at me. Bro. I'm dead.”
