The attraction between dueling Voice coaches-turned-couple Gwen Stefani and Blake Shelton is so very real that they began dating in real life—and you can see their crazy chemistry in action in the No Doubt frontwoman's big return to the show in her new role as adviser to Shelton's team.
Seriously, press play on the clip above to watch the sparks fly between the two singers as Stefani helps young singers Paxton Ingram and Brittney Lawrence take on Shawn Mendes and Camila Cabello's duet "I Know What You Did Last Summer."
"I knew you were coming back for season 10," Shelton slyly says to Stefani.
In an interview, he adds, "I brought Gwen in because if there's anybody who understands what a Battle Round is, it's somebody who's been a coach. She knows what it takes to win this thing."
