Blake Shelton says Adam Levine is an ''honest and loyal friend''.

The 37-year-old Maroon 5 singer was honoured with a star on the Hollywood Walk of Fame on Friday night (10.02.17), and his close friend Blake Shelton - with whom he works as a judge on American singing competition 'The Voice' - took to the stage to offer a heart warming speech where he spoke about how ''proud'' he was of his friend.

Blake said: ''Imagine my disappointment when I found out this wasn't a roast.

''If you would have told me that this guy would end up being one of my best friends, I would have called you crazy. 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. I love you.''

Meanwhile, Blake - who is in a relationship with Gwen Stefani - previously said he would happily trade lives with the 'Don't Wanna Know' singer ''because of his wife'' Behati Prinsloo.

He said at the time when asked who he would like to trade lives with: ''There's a lot of good options. [But] I'm gonna say I would pick Adam because he's married to a supermodel. Need I say more?''

''I don't give a f**k. That's who I'm picking and it's because of his wife. Period.''
