They've been together just shy of a year, and now, Gwen Stefani and Blake Shelton may be getting a presidential seal of aproval on their romance after the pair performed their hit duet during President Obama's final State Dinner at the White House last night.

Stefani was a featured performer at the dinner, which was in honor of Italian Prime Minister Matteo Renzi and his wife, Agnese Landini. Stefani's father is of Italian descent.

Stefani took the stage at the dinner to perform some of her biggest hits, including "The Sweet Escape," before then inviting her boyfriend, Shelton, onstage with her, to perform their duet from his new album, "Go Ahead and Break My Heart."

The pair was also able to mingle among celebrity guests at the event including Chance the Rapper, Vice President Joe Biden, President Obama and FLOTUS Michelle Obama, Giorgio Armani, Rachel Ray, James Taylor, Frank Ocean, and New York State Governer Andrew Cuomo and his girlfriend Sandra Lee, who they were snapped having a conversation with later. Stefani also shared a photo of herself with the President on Instagram.

The couple first went public with their romance last November, after months of speculation that they had begun dating when they reunited on the set of The Voice, following announcements that they were getting divorces from Miranda Lambert and Gavin Rossdale earlier that year. Since going public, the two have seemed virtually inseperable, and recorded the duet together for Shelton's If I'm Honest album.

There have also been several rumors since they went public that the two were trying to take their relationship to the next level by having a baby (which they have denied multiple times), and that they were making plans to marry, most recently with plans for a Christmas wedding. That report has not been explicitly confirmed or denied by either one of them.
