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

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."
The crowd was definitely feeling the love -- Stefani included! The singer couldn't help but Snapchat her "babes" while watching the ceremony.

Another "babe" Stefani couldn't get enough of? That would be Levine's baby girl, Dusty Rose, as she sat next to his wife, Behati Prinsloo.

And of course Stefani couldn't leave before getting in a photo op with Shelton and the man of the hour.

Stefani is clearly jelling with her Voice crew, just like old times. See the mother of three goof off on set in the video below.
