Gwen Stefani Tells Blake Shelton to 'Be Nice' Before Adam Levine's Walk of Fame Ceremony

'Imagine my disappointment when I found out this wasn't a roast,' Shelton said when he took the mic.

Gwen Stefani knows her boys!

The 47-year-old singer attended Adam Levine's Hollywood Walk of Fame Ceremony with Blake Shelton on Friday -- but knew better than to let her beau take the mic without a warning.

"Be nice!" Stefani yelled at Shelton before he walked up to the stage to give a speech in Levine's honor, though it seems he ignored her advice -- at least at first.

"Imagine my disappointment when I found out this wasn't a roast," Shelton cracked, before getting sentimental about his bromance with Levine.

"If you would have told me that this guy would end up being one of my best friends, I would have called you crazy," he said after telling the story of how they first met on The Voice. "But I have seen a lot of ups and downs, and I have never had a more honest and loyal friend than Adam Levine through my personal journey."

"We all know he is a huge star with music and movies and television, but I am happy to see him get this, because he is my friend and nobody is more shocked -- I mean proud -- than I am that he is going to have a star on the Hollywood Walk of Fame forever. Congratulations, brother," he sweetly concluded. "I love you."
